July 18, 2001


Dear Stockholders:


     You are cordially invited to attend a special meeting of the stockholders
of MiniMed Inc. (the "Company"), which will be held on Wednesday, August 22,
2001 beginning at 10:00 a.m. (PDT), at the Warner Center Marriott, Grand
Ballroom, 21850 Oxnard Street, Woodland Hills, California 91367.



     At the special meeting, you will be asked to consider and vote upon the
adoption of the Amended and Restated Agreement and Plan of Merger, dated as of
June 19, 2001, by and among the Company, Medtronic, Inc. and MMI Merger Sub,
Inc., a wholly-owned merger subsidiary of Medtronic. Under the Agreement and
Plan of Merger:


     - MMI Merger Sub, Inc. will merge with and into the Company;

     - the Company will continue as the corporation surviving the proposed
       merger and will become a wholly-owned subsidiary of Medtronic; and


     - each share of Company common stock issued and outstanding at the
       effective time of the proposed merger (other than shares held by the
       Company, Medtronic, MMI Merger Sub, Inc. or any direct or indirect
       wholly-owned subsidiary of the Company or Medtronic, which will be
       canceled without payment, and shares held by stockholders who perfect
       appraisal rights under Delaware law) will be converted into the right to
       receive $48 per share in cash, without interest.


     A Special Committee of the Board of Directors of the Company has
unanimously approved the Amended and Restated Agreement and Plan of Merger and
recommended that the Board of Directors of the Company approve, and the
stockholders of the Company vote to adopt, the Amended and Restated Agreement
and Plan of Merger. The Special Committee consists solely of directors who are
not officers or employees of the Company. The Board of Directors has unanimously
approved the Amended and Restated Agreement and Plan of Merger and declared its
advisability. Therefore, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU
VOTE IN FAVOR OF ADOPTING THE AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER.


     Completion of the proposed merger is subject to the satisfaction or valid
waiver of a number of conditions, including, among others, obtaining certain
necessary approvals and consents, and the expiration or termination of any
applicable waiting periods under any applicable foreign merger laws. Therefore,
even if the Company's stockholders adopt the Amended and Restated Agreement and
Plan of Merger, we cannot assure you that the proposed merger will be completed.


     The accompanying notice of special meeting and proxy statement explain the
proposed merger and a related proposal to allow us to adjourn or postpone the
special meeting, if needed, to solicit additional votes to adopt the Amended and
Restated Agreement and Plan of Merger, and contain specific information
concerning the special meeting. Please read these materials carefully, and
please do not send any stock certificates at this time.


     The Company cannot complete the proposed merger unless the holders of a
majority of the outstanding shares of Company common stock adopt the Amended and
Restated Agreement and Plan of Merger. Accordingly, failing to vote in favor of
the adoption of the Amended and Restated Agreement

   3

and Plan of Merger will have the same effect as a vote against the adoption of
the Amended and Restated Agreement and Plan of Merger.

     Your vote is very important, regardless of the number of shares you own.
Whether or not you plan to attend the special meeting, I urge you to complete,
sign and promptly return the enclosed proxy card to ensure that your shares will
be voted at the special meeting. If you decide to attend the special meeting,
you may withdraw your proxy at that time and vote your shares in person, if you
wish.

     On behalf of the Board of Directors, I thank you for your continued support
of the Company and ask that you vote FOR the adoption of the Amended and
Restated Agreement and Plan of Merger.

     I look forward to seeing you at the special meeting.

                                          Sincerely,

                                          /s/ ALFRED E. MANN

                                          Executive Chairman


     This proxy statement is dated July 18, 2001, and is first being mailed to
the Company's stockholders on July 23, 2001.

                               SUMMARY TERM SHEET


     This summary term sheet highlights selected information contained in this
proxy statement and may not contain all of the information that is important to
you. We urge you to read this entire proxy statement carefully, including the
attached appendices. In this proxy statement, we refer to MiniMed Inc. as the
"Company," and the terms "we," "us" and "our" also refer to the Company. We
refer to Medtronic, Inc. as "Medtronic" and we refer to MMI Merger Sub, Inc.,
the wholly-owned subsidiary of Medtronic which will be merged with and into the
Company, as the "merger subsidiary." We refer to the merger of the merger
subsidiary with and into the Company as the "Merger." We refer to the Agreement
and Plan of Merger, dated as of May 30, 2001, among the Company, Medtronic and
the merger subsidiary, as amended and restated by the Amended and Restated
Agreement and Plan of Merger, dated as of June 19, 2001 among the same parties
as the "Merger Agreement."


     - Stockholder Vote -- You are being asked to adopt the Merger Agreement, by
       which Medtronic will acquire the Company through a merger of the merger
       subsidiary with and into the Company. The Company will survive the Merger
       as a wholly-owned subsidiary of Medtronic. The Merger Agreement must be
       adopted by the affirmative vote of a majority of the outstanding shares
       of Company common stock. See "THE SPECIAL MEETING."


     - Recommendations -- A special committee of members of the Board of
       Directors of the Company who are not officers or employees of the Company
       (which we refer to in this proxy statement as the "Special Committee")
       has unanimously approved the Merger Agreement and has recommended that
       the Board of Directors of the Company approve, and the stockholders of
       the Company vote to adopt, the Merger Agreement. The Board of Directors
       unanimously recommends that the Company's stockholders vote FOR the
       adoption of the Merger Agreement. See "SPECIAL FACTORS -- Background of
       the Merger" and "-- Reasons for the Merger."



     - Payment -- In the Merger, each share of Company common stock owned by the
       Company's public stockholders will be canceled and converted into the
       right to receive $48 in cash, without interest and minus any required
       withholding for tax, except for shares held by stockholders who perfect
       appraisal rights under Delaware law. You will not own any Company common
       stock after completion of the Merger, even if you demand and perfect
       appraisal rights under Delaware law. See "THE MERGER AGREEMENT -- Merger
       Consideration."


     - Treatment of Options -- Options outstanding under the Company's stock
       option plans will become fully exercisable when the Merger becomes
       effective. Option holders who exercise their options prior to or at the
       effective time of the Merger will receive $48 per share in cash pursuant
       to the Merger for the shares of Company common stock issued upon exercise
       of the options (without interest and minus any required withholding for
       tax). The Company will establish a procedure for option holders who
       exercise their options effective at the effective time of the Merger to
       elect to avoid payment of the exercise price in cash and receive the
       difference between $48 and the exercise price for each share as to which
       the option is exercised. Any options not exercised prior to or at the
       effective time of the Merger will be assumed by Medtronic and will be
       exercisable after the Merger to purchase shares of Medtronic common
       stock. See "THE MERGER AGREEMENT -- Treatment of Stock Options."

     - Tax Consequences -- Generally, the Merger will be taxable for U.S.
       federal income tax purposes. You will recognize taxable gain or loss in
       the amount of the difference between the $48 cash price per share
       proposed to be paid pursuant to the Merger and your adjusted tax basis
       for each share of Company common stock that you own. See "SPECIAL
       FACTORS -- Material Federal Income Tax Consequences to Stockholders."

     - Conditions to the Merger -- The Merger Agreement is subject to adoption
       by the Company's stockholders in accordance with applicable law, as well
       as the satisfaction or valid waiver of other conditions, including, among
       others, the expiration or termination of applicable waiting periods under
       the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
       (which we call the

                                        i
   6


       "HSR Act"), and under applicable foreign merger laws. On Friday, July 13,
       2001, the waiting period under the HSR Act was terminated prior to its
       normal expiration date with respect to both the Merger and the proposed
       merger transaction involving Medtronic and Medical Research Group. See
       "THE MERGER AGREEMENT -- Conditions to Completing the Merger."


     - Appraisal Rights -- Stockholders who neither vote in favor of nor consent
       in writing to the Merger will be entitled to seek an appraisal of the
       "fair value" of their shares under Delaware law, exclusive of any element
       of value arising from the expectation or accomplishment of the Merger. In
       order to perfect the right to an appraisal, a stockholder must submit a
       timely written demand for appraisal and otherwise comply with the
       applicable requirements of Delaware law. See "SPECIAL
       FACTORS -- Appraisal Rights."

                QUESTIONS AND ANSWERS ABOUT THE PROPOSED MERGER
                            AND THE SPECIAL MEETING

     The following questions and answers are for your convenience only, and
briefly address some commonly asked questions about the proposed Merger and the
special meeting. You should still carefully read this entire proxy statement,
including each of the attached appendices.

Q: WHAT AM I BEING ASKED TO VOTE ON?

A: You are being asked to adopt the Merger Agreement that provides for the
   merger of the merger subsidiary with and into the Company. The merger
   subsidiary is a newly-formed Delaware corporation that Medtronic formed to
   acquire the Company through the Merger.

Q: WHAT WILL I BE ENTITLED TO RECEIVE FOR MY COMPANY COMMON STOCK IF THE
   PROPOSED MERGER IS COMPLETED?

A: Pursuant to the Merger, each issued and outstanding share of Company common
   stock automatically will be canceled and converted into the right to receive
   $48 per share in cash, without interest and minus any required withholding
   for tax, with the following exceptions:

   - each share of Company common stock owned by the Company, Medtronic, the
     merger subsidiary, or any other wholly-owned subsidiary of the Company or
     Medtronic automatically will be canceled in the Merger without any payment;
     and


   - each share of Company common stock held by Company stockholders who
     properly perfect their appraisal rights under Delaware law will be entitled
     to an appraisal by the Delaware Court of Chancery to determine the "fair
     value" of those shares in accordance with Delaware law, exclusive of any
     element of value arising from the expectation or accomplishment of the
     Merger.


Q: WHAT VOTE IS REQUIRED TO ADOPT THE MERGER AGREEMENT?

A: The Merger Agreement must be adopted by the holders of a majority of the
   outstanding shares of Company common stock. The holders of approximately 27%
   of the outstanding shares of Company common stock, including Alfred E. Mann,
   the founder and Executive Chairman of the Company, have entered into
   agreements with Medtronic to vote shares beneficially owned by them in favor
   of the approval, consent and ratification of the Merger Agreement and the
   Merger and against any action that could impede, interfere with, frustrate,
   nullify or discourage the Merger, could facilitate the acquisition of the
   Company by a party other than Medtronic or could reasonably result in any of
   the conditions to the obligations of the Company under the Merger Agreement
   not being fulfilled. These agreements do not limit Mr. Mann's ability to act
   consistently with his fiduciary obligations in his capacity as an officer or
   director of the Company.

Q: WHEN AND WHERE IS THE SPECIAL MEETING?


A: The special meeting will be held on Wednesday, August 22, 2001 beginning at
   10:00 a.m. (PDT), at the Warner Center Marriott, Grand Ballroom, 21850 Oxnard
   Street, Woodland Hills, California 91367.


Q: WHO CAN VOTE AT THE SPECIAL MEETING?


A: Holders of Company common stock at the close of business on Monday, July 16,
   2001, the record date for the special meeting, are entitled to vote in person
   or by proxy at the special meeting. Each stockholder is entitled to one vote
   per share of Company common stock owned of record on that date. There were
   64,833,274 shares of Company common stock issued and outstanding at the close
   of business on Monday, July 16, 2001.

   10

Q: WHAT IS THE PROXY CARD THAT IS ENCLOSED WITH THE PROXY STATEMENT?

A: The proxy card enables you to appoint Terrance H. Gregg and Eric S. Kentor as
   your representatives at the special meeting. By completing and returning the
   proxy card, you are authorizing Terrance H. Gregg or Eric S. Kentor to vote
   your shares at the special meeting, as you have instructed them on the proxy
   card, whether or not you attend the special meeting. Even if you plan to
   attend the special meeting, it is a good idea to complete and return your
   proxy card before the date of the special meeting, just in case your plans
   change.

Q: WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE PROXY CARD?

A: It probably means that you have multiple accounts holding shares of Company
   common stock at the transfer agent or with stockbrokers. You should complete
   and return all proxy cards you receive in order to ensure that all your
   shares are voted.

Q: HOW MANY SHARES MUST BE PRESENT TO HOLD THE SPECIAL MEETING?

A: To hold the special meeting of the stockholders and conduct business, a
   majority of the Company's outstanding shares as of the record date must be
   present at the special meeting. This is called a quorum. Shares are counted
   as present at the special meeting if:

   - the stockholder is present in person and entitled to vote at the special
     meeting;

   - the stockholder has properly submitted a proxy card; or

   - a brokerage firm has submitted a proxy for shares that are held in street
     name as described below.

Q: WHY IS THE BOARD OF DIRECTORS RECOMMENDING THAT I VOTE TO ADOPT THE MERGER
   AGREEMENT?


A: The Special Committee, which is comprised of members of the Board of
   Directors who are not officers or employees of the Company, has unanimously
   determined that the terms of the Merger Agreement and the Merger are
   advisable, fair to, and in the best interests of, the Company and its
   stockholders. Based in part on the Special Committee's recommendation, the
   Board of Directors unanimously recommends that you vote FOR the adoption of
   the Merger Agreement. See "SPECIAL FACTORS -- Reasons for the Merger."


Q: IS THE MERGER SUBJECT TO ANY CONDITIONS?

A: Yes. Before the transactions contemplated by the Merger Agreement can be
   completed, certain conditions must be satisfied or waived. These closing
   conditions include, among others:

   - obtaining any necessary approvals and consents to the Merger and the
     expiration or termination of any applicable waiting periods under the HSR
     Act and under any applicable foreign merger laws with respect to required
     filings in connection with the Merger and the proposed merger transaction
     involving Medical Research Group and Medtronic;


   - no change, event, occurrence, state of facts or development can have had,
     or could be reasonably expected to have, a "material adverse effect" (as
     defined below under "SUMMARY -- Conditions to the Merger" on page 11) on
     the Company;


   - the representations and warranties made by Medical Research Group, Inc. in
     its merger agreement with Medtronic entered into on the same date as the
     Company's Merger Agreement with Medtronic must be true and correct in all
     material respects and there must not have been any change, event,
     occurrence, state of facts or development with respect to Medical Research
     Group that has had or could reasonably be expected to have a "material
     adverse effect" (as defined below under "SUMMARY -- Conditions to the
     Merger" on page 11) on the Company and Medical Research Group, taken
     together as a whole.

                                        2
   11


   On Friday, July 13, 2001, the waiting period under the HSR Act was terminated
   prior to its normal expiration date with respect to both the Merger and the
   proposed merger transaction involving Medical Research Group and Medtronic.



   These and other conditions are discussed in greater detail on page 55 of this
   proxy statement in the section entitled "THE MERGER AGREEMENT -- Conditions
   to Completing the Merger." If these and the other conditions described
   elsewhere in this proxy statement are not satisfied or validly waived, the
   proposed Merger will not be completed, even if the Company's stockholders
   vote to adopt the Merger Agreement.


Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?


A: We are working to complete the Merger as quickly as possible. In addition to
   stockholder approvals, we must comply with applicable foreign merger laws
   with respect to the Merger and the proposed merger transaction involving
   Medical Research Group and Medtronic. If the conditions to the Merger are
   satisfied or validly waived, we hope to complete the Merger shortly after the
   special meeting.


Q: WILL I OWE ANY U.S. FEDERAL INCOME TAX AS A RESULT OF THE MERGER?

A: The receipt of cash for shares of common stock pursuant to the Merger will be
   a taxable transaction for U.S. federal income tax purposes, and may also be a
   taxable transaction under applicable state, local, foreign or other tax laws.
   Generally, you will recognize gain or loss for these purposes equal to the
   difference between $48 per share and your adjusted tax basis for the shares
   of Company common stock you own immediately prior to the Merger. For U.S.
   federal income tax purposes, this gain or loss generally would be a capital
   gain or loss if you held the shares of common stock as a capital asset.


   TAX MATTERS ARE VERY COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO
   YOU WILL DEPEND ON THE FACTS OF YOUR PARTICULAR SITUATION. YOU SHOULD CONSULT
   YOUR TAX AND OTHER ADVISORS FOR A FULL UNDERSTANDING OF THE CONSEQUENCES OF
   THE PROPOSED MERGER TO YOU.


Q: HOW DO I VOTE MY SHARES?


A: YOU MAY AUTHORIZE THE PROXY HOLDERS TO VOTE FOR YOU. After you have carefully
   reviewed this entire proxy statement, including the attached appendices,
   please mark your vote on the enclosed proxy card and sign it and mail it to
   the Company in the enclosed, prepaid and addressed envelope as soon as
   possible. Doing so will ensure that your shares will be voted at the special
   meeting. If you mark your voting instructions on the proxy card, your shares
   will be voted by the proxy holders as you instruct. If you sign and return
   the proxy card and do not indicate how you want to vote, your shares will be
   voted FOR the adoption of the Merger Agreement and, if additional votes are
   necessary to adopt the Merger Agreement, FOR the "adjournment proposal"
   described below in the section entitled "[w]hat other matters will be voted
   on at the special meeting."


   YOU MAY VOTE IN PERSON. We will pass out written ballots to anyone who is
   entitled to and wants to vote at the special meeting. However, if your shares
   are not held in your name, you must request a proxy from the registered
   holder. Typically, shares purchased through a stockbroker are held in the
   name of an entity designated by the brokerage firm, which is referred to as a
   "street name" holder. Any shares held in "street name" cannot be voted
   without a proxy obtained from your broker.

Q: WILL MY SHARES BE VOTED IF I DO NOT SIGN AND RETURN MY PROXY CARD?


A: If you do not sign and return the enclosed proxy card and you do not
   otherwise sign a proxy from your broker (for any shares held in "street
   name") or vote your shares in person at the special meeting, your shares will
   not be voted. If your shares are not voted, it will have the same effect as a
   vote AGAINST the adoption of the Merger Agreement.


                                        3
   12

Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
   SHARES FOR ME?


A: Your broker will vote your shares held in "street name" only if you provide
   written instructions as to how you want your shares voted. You should follow
   the directions provided by your broker regarding how to instruct your broker
   to vote your shares. Without instructions, your shares held in "street name"
   will not be voted by your broker, and the failure to vote your shares will
   have the same effect as a vote AGAINST the adoption of the Merger Agreement.


Q: DO I HAVE APPRAISAL RIGHTS WITH RESPECT TO THE MERGER?


A: If you wish, you may dissent from the Merger and seek an appraisal of the
   "fair value" of your shares in connection with the Merger (excluding any
   element of value arising from the accomplishment or expectation of the
   Merger), but only if you comply with all of the requirements for seeking an
   appraisal under Delaware law. The requirements under Delaware law are
   summarized on pages 44 through 47 of this proxy statement. The full text of
   Section 262 of the General Corporation Law of the State of Delaware, which
   governs stockholder rights to appraisal and specifies the requirements for
   seeking an appraisal, is set forth in the attached Appendix D. You should
   read these materials in their entirety so that you fully understand your
   rights to demand an appraisal of the "fair value" of your shares and
   understand the procedure to properly perfect those rights. You are also
   encouraged to consult your own legal counsel if you want assistance in
   perfecting your appraisal rights.


Q: CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You may revoke your proxy and change your vote at any time before the
   polls close at the special meeting. If you are the record holder of your
   shares, you can do this in one of three ways:

   - Prior to the special meeting, you can sign a written notice of your intent
     to revoke your proxy and deliver it to the Company at: MiniMed Inc., 18000
     Devonshire Street, Northridge California 91325, Attention: Eric S. Kentor,
     Secretary. The notice of revocation must be received before the vote is
     taken at the special meeting.

   - You can sign another proxy card with a later date and deliver it to the
     Secretary of the Company at or before the special meeting.

   - You can attend the special meeting and vote your shares in person. If you
     choose this method of revoking your original proxy, you must actually vote
     your shares in person at the special meeting. If you attend the special
     meeting but do not actually vote your shares, your original proxy will not
     be revoked solely because you attended the special meeting in person.

Q: HOW CAN I CHANGE MY VOTE AFTER I INSTRUCT MY BROKER TO VOTE MY SHARES HELD IN
   "STREET NAME"?

A: If you hold your shares in "street name" and have instructed your broker to
   vote your shares, you must follow the directions received from your broker as
   to how to change your vote.

Q: WHAT OTHER MATTERS WILL BE VOTED ON AT THE SPECIAL MEETING?


A: In addition to asking you to vote on the adoption of the Merger Agreement, we
   are asking you to consider and vote on a proposal to permit the Company to
   adjourn or postpone the special meeting to permit further solicitation of
   proxies in the event that there are not sufficient votes at the time of the
   special meeting to adopt the Merger Agreement. We refer to this as the
   "adjournment proposal". The vote for adoption of the Merger Agreement is
   separate from the vote for the adjournment proposal. Assuming a quorum is
   present, the affirmative vote of a majority of the shares of Company common
   stock present in person or represented by proxy at the special meeting is
   necessary to approve the adjournment proposal.


   Other than the proposal to adopt the Merger Agreement and the adjournment
   proposal, we do not expect to ask you to vote on any other matters at the
   special meeting. However, if matters other than

                                        4
   13

   the proposal to adopt the Merger Agreement and the adjournment proposal are
   properly brought before the special meeting, or any adjournments or
   postponements of the special meeting, the persons appointed as proxies will
   have discretion to vote or act on those matters according to their best
   judgment.

Q: HAS THE COMPANY HIRED ANYONE TO SOLICIT PROXIES IN CONNECTION WITH THE
   SPECIAL MEETING?

A: The Company has hired Morrow & Co., Inc. to solicit proxies in connection
   with the Special Meeting. The terms of the Company's arrangement with Morrow
   & Co., Inc. are described in the section entitled "Solicitation; Revocation
   and Use of Proxies" on pages 19 and 20.

Q: WHO CAN I CONTACT IF I HAVE OTHER QUESTIONS?

A: The information provided above in "question and answer" format is for your
   convenience only and is merely a summary of some of the information contained
   in this proxy statement. You should carefully read the entire proxy
   statement, including each of the attached appendices.

THE MERGER

(See Pages 48 and 49)


     In the proposed Merger, each share of Company common stock issued and
outstanding as of the effective time of the Merger automatically will be
canceled and converted into the right to receive $48 per share in cash, without
interest and minus any required withholding for tax, with the following
exceptions:

     - shares held by the Company as treasury stock and shares owned by
       Medtronic, the merger subsidiary or any direct or indirect wholly-owned
       subsidiary of Medtronic or the Company automatically will be canceled
       without payment at the effective time of the Merger; and


     - shares held by Company stockholders who have properly perfected appraisal
       rights under Delaware law will be subject to appraisal of their "fair
       value" determined in accordance with Delaware law.


     Options outstanding under the Company's stock option plans will become
fully exercisable when the Merger becomes effective. Option holders who exercise
their options prior to or at the effective time of the Merger will receive
pursuant to the Merger $48 per share in cash for the shares of Company common
stock issued upon exercise of the options (without interest and minus any
required withholding for tax). The Company will establish a procedure for option
holders who exercise their options effective at the effective time of the Merger
to elect to avoid payment of the exercise price in cash and receive the
difference between $48 and the exercise price for each share as to which the
option is exercised. Any options not exercised prior to or at the effective time
of the Merger will be assumed by Medtronic and will be exercisable after the
merger to purchase shares of Medtronic common stock. See "THE MERGER
AGREEMENT -- Treatment of Stock Options."


     The exercise dates of options under the Company's Employee Stock Purchase
Plan also will be accelerated and such options automatically will be exercised
(other than options held by any person who withdraws from the plan prior to the
automatic exercise of that person's options), and each share of Company common
stock issued upon exercise of the options automatically will be converted into
the right to receive $48 per share in cash (without interest and minus any
required withholding for tax). See "THE MERGER AGREEMENT -- Treatment of ESPP
Options."


OUR RECOMMENDATIONS TO STOCKHOLDERS
(See Pages 22 through 32)

     The Special Committee has unanimously approved the Merger Agreement and
recommended that the Board of Directors approve, and the stockholders of the
Company vote to adopt, the Merger Agreement. The Special Committee consists
solely of directors who are not officers or employees of the Company. Based in
part on the Special Committee's recommendation, the Board of Directors has also
unanimously approved the Merger Agreement and declared its advisability.
Therefore, the Board of Directors unanimously recommends that you vote FOR the
adoption of the Merger Agreement. For additional information regarding these
recommendations, see "SPECIAL FACTORS -- Background of the Merger" and "Reasons
for the Merger."

OPINIONS OF FINANCIAL ADVISORS
(See Pages 32 through 40)

     In connection with the Merger, the Board of Directors received a written
opinion from UBS Warburg LLC as to the fairness, from a financial point of view,
of the merger consideration to be received by the holders of Company common
stock. The full text of UBS Warburg's written opinion dated May 30, 2001 is
attached to this proxy statement as Appendix B. We encourage you to read this
opinion carefully and in its entirety for a description of the assumptions made,
procedures followed, matters considered and limitations on the review undertaken
by UBS Warburg. UBS WARBURG'S OPINION IS ADDRESSED TO THE BOARD OF DIRECTORS AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY COMPANY STOCKHOLDER WITH RESPECT TO
ANY MATTERS RELATING TO THE PROPOSED MERGER.

     U.S. Bancorp Piper Jaffray Inc. also has given a written opinion, dated May
29, 2001, to the Special Committee as to the fairness, from a financial point of
view, of the merger consideration to be received by the Company's stockholders,
other than Medtronic and its affiliates, in the Merger. The full text of this
opinion is attached to this proxy statement as Appendix C. You should read the
opinion carefully in its entirety to understand the procedures followed,
assumptions made, matters considered and limitations on the review undertaken by
U.S. Bancorp Piper Jaffray in providing its opinion. THE OPINION OF U.S. BANCORP
PIPER JAFFRAY IS ADDRESSED TO THE SPECIAL COMMITTEE AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY COMPANY STOCKHOLDER WITH RESPECT TO ANY MATTERS RELATING
TO THE MERGER.

INTERESTS OF THE COMPANY'S DIRECTORS AND OFFICERS IN THE MERGER
(See Pages 41 through 43)

     When considering the recommendation of the Company's Board of Directors
with respect to the Merger, you should be aware that Alfred E. Mann, the
Company's founder, Executive Chairman and largest stockholder, has an interest
in the Merger that is different from your interests as a Company stockholder.
Mr. Mann is also the founder, Chairman and a principal stockholder of Medical
Research Group, which has also entered into a separate merger agreement with
Medtronic under which Medical Research Group would be acquired for approximately
$420 million in cash and/or Medtronic common stock. Mr. Mann and a corporation
wholly-owned by him beneficially own approximately 32% of the outstanding shares
of Medical Research Group, and charitable organizations established or endowed
by him own approximately 30% of the outstanding shares of Medical Research
Group. Medical Research Group manufactures an implantable insulin pump and is
developing a long-term glucose monitoring system. The Company has the exclusive
worldwide marketing rights to the implantable pump for insulin and to the
long-term glucose sensor system and has a number of contractual rights and
obligations under agreements with Medical Research Group. Because of these
relationships between the Company and Medical Research Group, Medtronic insisted
on signing merger agreements with both companies concurrently.

     Certain directors and executive officers of the Company hold options under
the Company's 1994 option plan. The exercise dates of these options will
accelerate and, if the options are exercised, those directors and executive
officers will be entitled to receive $48 per share (less the relevant exercise
price and applicable taxes) in connection with the Merger on the same terms and
subject to the same conditions that apply to other holders of options under the
1994 option plan. Options which are not exercised at or prior to the effective
time of the Merger will be assumed by Medtronic and after the Merger will be
exercisable to purchase shares of Medtronic common stock. See "THE MERGER
AGREEMENT -- Treatment of Stock Options."

     In addition, certain directors of the Company hold Non-Employee Director
Deferred Stock Units under the Company's Non-Employee Director Deferred Stock
Units Plan, which will be converted into the right to receive $48 per unit in
cash, without interest and minus any required withholding for tax. See "THE
MERGER AGREEMENT -- Treatment of Deferred Stock Units."


     The Merger Agreement provides that the directors and officers of the
Company will have certain rights to indemnification and limitation of liability
for certain acts and advancement of fees and expenses of defending certain legal
claims. In addition, Medtronic has agreed to maintain the benefits of the
Company's directors' and officers' liability insurance policy, or provide
similar coverage, for three years after the effective time of the Merger,
subject only to certain premium limitations. See "THE MERGER
AGREEMENT -- Director and Officer Liability."



     Further, in the past, the Company entered into change of control agreements
under which a number of its executive officers may be entitled to receive cash
compensation and continuation of benefits in the event of a change of control
such as the Merger. The terms of those agreements are described in "SPECIAL
FACTORS -- Interests of the Company's Directors and Officers in the Merger." In
addition, in connection with the Merger Agreement, four officers of the Company,
Messrs. Terrance H. Gregg, Kevin R. Sayer, David H. Morley and Stephen A. Bowman
entered into agreements not to compete with


                                        8
   17

Medtronic for the longer of five years after the effective date of the Merger or
two years after the termination of their employment with the Company or
Medtronic.

     David H. MacCallum, a director of the Company, is the Global Head of Health
Care Investment Banking at Salomon Smith Barney Inc., which provided certain
services to the Company in connection with the Merger, for which Salomon Smith
Barney will be paid a fee as described in "SPECIAL FACTORS -- Interests of the
Company's Directors and Officers in the Merger."

     The members of the Special Committee are entitled to a special fee for
their services, in addition to their normal per-meeting fees as directors. This
special fee is not contingent on the completion of the Merger or any other
transaction. See "SPECIAL FACTORS -- Interests of the Company's Directors and
Officers in the Merger."

FINANCING FOR THE MERGER
(See Page 43)

     Medtronic and the merger subsidiary estimate that approximately $3.3
billion will be required to complete the Merger and to pay the related fees and
expenses. Medtronic and the merger subsidiary expect to fund this amount through
cash on hand, available borrowing capacity, debt financing and other financing
alternatives that may become available to Medtronic.

RECORD DATE; VOTING POWER

(See Pages 18 through 20)



     At the special meeting, you will be entitled to one vote for each share of
Company common stock you held of record as of the close of business on July 16,
2001.



     The Merger Agreement must be adopted by the holders of a majority of the
outstanding shares of Company common stock. On the record date, there were
64,833,274 shares of Company common stock entitled to vote at the special
meeting.



     We do not expect to ask you to vote on any matters at the special meeting
other than the adoption of the Merger Agreement and, if needed, the proposal to
adjourn the special meeting to permit the solicitation of additional proxies to
adopt the Merger Agreement. However, if any other matters are properly presented
at the special meeting for consideration, the holder of the proxies will have
discretion to vote on those matters in accordance with his or her best judgment.
These matters may include an adjournment or postponement of the special meeting
from time to time if our Board of Directors so determines. If any adjournment or
postponement is made and the adjournment proposal has been approved, we may
solicit additional proxies during the adjournment period.



     As of the record date for the special meeting, the Company's directors and
executive officers beneficially owned an aggregate of 13,925,178 of the
outstanding shares of Company common stock, representing approximately 21.48% of
the issued and outstanding shares of Company common stock as of the record date
for the special meeting. The Company's directors and executive officers have
indicated that they intend to vote all of the shares of Company common stock
beneficially owned by them FOR the adoption of the Merger Agreement.



     In addition, Alfred E. Mann, two corporations wholly-owned by Mr. Mann, the
Alfred E. Mann Charitable Remainder Trust, the Alfred Mann Foundation and the
Alfred E. Mann Institute for Biomedical Engineering at the University of
Southern California executed Agreements to Facilitate the Merger, including the
obligation to vote their shares of Company common stock in favor of the
approval, consent and ratification of the Merger Agreement and the Merger and
against any proposal or action that could impede, interfere with, frustrate,
nullify or discourage the Merger, could facilitate the acquisition of the
Company by a party other than Medtronic or could reasonably result in any of the
conditions to the obligations of the Company under the Merger Agreement not
being fulfilled. These agreements do not limit Mr. Mann's ability to act
consistently with his fiduciary obligations in his capacity as an officer and
director of the Company. The number of shares of Company common stock
beneficially owned by persons

                                        9
   18

signing these agreements constitutes approximately 27% of the number of shares
of Company common stock outstanding.

THE MERGER AGREEMENT
(See Pages 48 through 58)

     The Merger Agreement, including the significant conditions to the closing
of the Merger, is described on pages 48 through 58 of this proxy statement and
is attached as Appendix A to this proxy statement. You should carefully read the
entire Merger Agreement, as it is the legal document that governs the Merger.

APPRAISAL RIGHTS

(See Pages 44 through 47 and Appendix D)


     The Company is a corporation organized under Delaware law. Therefore, the
General Corporation Law of the State of Delaware governs when stockholders are
entitled to appraisal rights and what procedures are required to perfect any
available appraisal rights. Under Delaware law, if you do not vote in favor of
or consent in writing to the Merger, submit a timely written demand for
appraisal and follow all of the other procedures required for perfecting
appraisal rights described in pages 44 through 47 and in Appendix D to this
proxy statement, you will receive a cash payment for the "fair value" of your
shares, as determined by the Delaware Court of Chancery, instead of the $48 cash
payment to be received by stockholders who do not seek and perfect appraisal
rights in connection with the Merger. The price determined by the Delaware Court
of Chancery may be more than, the same as, or less than the $48 per share in
cash you would have received pursuant to the Merger if you had not exercised
your appraisal rights and will be determined without taking into account any
element of value arising from the expectation or accomplishment of the Merger.
Generally, in order to exercise appraisal rights, among other things:

     - You must NOT vote in favor of or consent in writing to the adoption of
       the Merger Agreement; and

     - You must make a written demand for appraisal rights in compliance with
       Delaware law BEFORE the vote to adopt the Merger Agreement.


     Merely voting against the adoption of the Merger Agreement will not
preserve or perfect your appraisal rights under Delaware law. Appendix D
attached to this proxy statement contains the complete text of Section 262 of
the General Corporation Law of the State of Delaware, which governs the
availability and perfection of appraisal rights under Delaware law.


     A proxy which does not contain voting instructions will, unless revoked, be
voted in favor of adoption of the Merger Agreement, and therefore, if you vote
by proxy and wish to exercise your appraisal rights, you must vote AGAINST the
adoption of the Merger Agreement or ABSTAIN from voting on the proposal to adopt
the Merger Agreement.

     If you want to exercise your appraisal rights, please read and carefully
follow the procedures described on pages 44 through 47 and set forth in full in
Appendix D. Failure to take all of the steps required to perfect your appraisal
rights under Delaware law may result in the loss of your appraisal rights. You
also are encouraged to seek the assistance of your own independent legal counsel
if you want help in perfecting your appraisal rights.

EFFECTS OF THE MERGER

(See Page 40)


     Upon completion of the Merger, Medtronic will own 100% of the outstanding
capital stock of the Company, which will survive the Merger as a wholly-owned
subsidiary of Medtronic. As a result, you will no longer be a stockholder of the
Company after the Merger, and you will not participate in any future

                                        10
   19


earnings, losses, growth or decline of the Company. Medtronic, as the sole
Company stockholder after the Merger, will be the sole beneficiary of the future
earnings and growth of the Company, if any.



     After the Merger, there will no longer be a public market for Company
common stock, and the Company common stock will no longer be quoted on the
Nasdaq National Market. In addition, the registration of Company common stock
under the Securities Exchange Act of 1934, as amended, as well as the Company's
obligations to file periodic reports with the Securities and Exchange
Commission, will be terminated.

       Merger or would impose any material limitation on the ability of
       Medtronic to effectively exercise full rights of ownership of the Company

       have, a "material adverse effect" on the Company, as defined below;

     - Medtronic must receive certificates signed by the chief executive officer
       of the Company stating that as of the closing date of the Merger the two

       together as a whole; and

     - all applicable waiting periods under the HSR Act and any applicable
       foreign merger laws relating to the transactions contemplated by the

together as a whole, or (b) the Company's ability to perform any of its material
obligations under the Merger Agreement or to consummate the Merger, or (c) the
ability of Medtronic or the Company as the corporation surviving the Merger, to
conduct the businesses of the Company and its subsidiaries taken as a whole as
previously conducted, or proposed to be conducted, or (d) the ability of
Medtronic or the Company as the corporation surviving the Merger to exercise

each case for any change, effect, event, occurrence, state of facts or

political conditions or (ii) changes in the medical device industry generally.

     If these conditions are not satisfied or waived, the Merger will not be
completed, even if our stockholders vote to adopt the Merger Agreement.

TERMINATION OF THE MERGER AGREEMENT

(See Pages 57 and 58)


     The Company and Medtronic may mutually agree to terminate the Merger
Agreement at any time before the effective time of the Merger, whether or not
the stockholders have voted to adopt the Merger Agreement. In addition, either
party may terminate the Merger Agreement if, among other things:

     - the Merger has not been completed by December 31, 2001, or such other
       date as the Company and Medtronic agree, subject to certain required
       extensions to as late as March 31, 2002 if additional information is
       requested in connection with the filings under the HSR Act or pursuant to
       any applicable foreign merger laws;

     - a court of competent jurisdiction or an administrative, governmental or
       regulatory authority in the United States or the European Union has taken
       any action having the effect of permanently restraining, enjoining or
       otherwise prohibiting the Merger;

     - the Company's stockholders do not adopt the Merger Agreement at the
       special meeting, except that no party can terminate the Merger Agreement
       for this reason if that party's actions caused, or resulted in, the
       failure of the Company's stockholders to adopt the Merger Agreement; or

                                        12
   21

     - the other party has materially breached any of its representations,
       warranties or obligations under the Merger Agreement and the party
       desiring to terminate the Merger Agreement is not in material breach of
       its representations, warranties or obligations; provided that the
       non-breaching party cannot terminate the Merger Agreement for this reason
       if the material breach can be cured by the breaching party with
       commercially reasonable efforts and the cure is reasonably likely to be
       completed before December 31, 2001 or such other date as the Company and
       Medtronic agree, in each case subject to the required extensions to as
       late as March 31, 2002 if additional information is requested in
       connection with the filings under the HSR Act or pursuant to any
       applicable foreign merger laws.

     In addition, Medtronic may terminate the Merger Agreement if, among other
things:

     - the Company breaches in any material respect its obligations under the
       Merger Agreement not to solicit, initiate or encourage other proposals to
       acquire the Company or participate in or encourage discussions or
       negotiations or provide non-public information concerning other
       acquisition proposals or facilitate or implement any such proposals;

     - the Board of Directors of the Company withdraws or modifies or amends its
       approval or recommendation of the Merger in any respect adverse to
       Medtronic or the merger subsidiary;

     - the Board of Directors of the Company recommends another proposal to
       acquire control of the Company or more than 20% of the Company's assets
       to the Company's stockholders or resolves or announces an intention to do
       so; or


     - a tender offer or exchange offer for 50% or more of the outstanding
       shares of Company common stock is announced or commenced and either the
       Board of Directors of the Company recommends acceptance of the offer by
       the Company's stockholders or the Board of Directors fails to recommend
       against acceptance of such offer within 10 business days after the offer
       commences.


     The Company may also terminate the Merger Agreement prior to the adoption
of the Merger Agreement by the Company's stockholders if the Company has
complied with all requirements, conditions and procedures regarding its
non-solicitation obligations under the Merger Agreement referred to above in all
material respects and if all of the following occur:

     - the Board of Directors of the Company has, upon the Special Committee's
       recommendation and in accordance with the provisions of the Merger
       Agreement, authorized the Company to enter into a binding written
       agreement that is a "superior proposal," as defined in the Merger
       Agreement and described in "THE MERGER AGREEMENT -- Limitations on
       Solicitation of Competing Proposals," and notifies Medtronic that it
       intends to enter into such an agreement;

     - Medtronic does not make, within five business days after receipt of the
       notice from the Company, a proposal that the Special Committee determines
       (reasonably and in good faith and after consultation with its legal and
       financial advisors) is at least as favorable to the Company's
       stockholders as the Superior Proposal;

     - during that five business day period the Company reasonably considers and
       discusses in good faith all proposals submitted by Medtronic and meets
       with and causes its financial and legal advisors to meet with Medtronic
       and its advisors to consider Medtronic's proposals; and

     - the Company pays Medtronic the termination fee of $108 million. See "THE
       MERGER AGREEMENT -- Termination Fee."

WHAT HAPPENS IF THE COMPANY RECEIVES ANOTHER ACQUISITION PROPOSAL?
(See Pages 52 through 54)

     The Merger Agreement provides that neither the Company nor its officers,
directors, advisors, representatives or other agents will, directly or
indirectly, solicit, initiate or knowingly encourage any "acquisition proposal"
or participate in or encourage any discussions or negotiations with, or provide
any

                                        13
   22

non-public information to, any person or entity concerning any "acquisition
proposal" or otherwise facilitate any effort or attempt to make or implement an
"acquisition proposal." An "acquisition proposal" is defined in the Merger
Agreement as any offer or proposal for any of the following transactions
concerning the Company or any subsidiary of the Company:

     - any tender offer, exchange offer, merger, consolidation, share exchange,
       business combination or similar transaction involving more than 50% of
       the capital stock of the Company or any subsidiary of the Company;

     - any transaction or series of related transactions pursuant to which any
       person or entity (including any entity's stockholders, but excluding
       Medtronic or the merger subsidiary or their respective affiliates)
       acquires shares, or securities convertible into or exercisable for
       shares, representing more than 50% of the outstanding shares of any class
       of capital stock of the Company or any subsidiary of the Company; or

     - any sale, lease, exchange, licensing, transfer or other disposition,
       whether in one transaction or a series of related transactions, pursuant
       to which any person or entity (including any entity's stockholders, but
       excluding Medtronic or the merger subsidiary or their respective
       affiliates) acquires control of more than 20% of the assets of the
       Company and its subsidiaries, taken as a whole, determined by reference
       to the fair market value of the assets.

     However, before the date that the Company's stockholders adopt the Merger
Agreement, the Special Committee may furnish non-public information to, or enter
into discussions or negotiations with, any party that makes an unsolicited
"superior proposal" if:

     - the failure of the Company's Board of Directors to take action with
       respect to the "superior proposal" would be a breach of the Board's
       fiduciary duties to the Company's stockholders imposed by applicable law;
       and

     - prior to furnishing any non-public information or entering into any
       negotiations or discussions regarding a "superior proposal," the Company
       (a) provides five business days advance written notice to Medtronic that
       it intends to do so and discloses the identity of the party making the
       "acquisition proposal," (b) receives a confidentiality agreement from the
       party making the "acquisition proposal" with terms no less favorable to
       the Company than the terms of the confidentiality agreement between the
       Company and Medtronic, and (c) concurrently provides Medtronic with any
       non-public information to be provided to the party making the
       "acquisition proposal" that was not previously provided to Medtronic.

     The Company must also keep Medtronic informed of the status, terms,
conditions and all other material information regarding any discussions or
negotiations relating to any "superior proposal" on at least a daily basis.

     A "superior proposal" is a bona fide acquisition proposal:

     - that the Special Committee reasonably and in good faith determines, with
       the advice of the Special Committee's financial advisors and taking into
       account all material legal, financial and regulatory aspects of the
       "superior proposal," is more favorable to the Company's stockholders than
       the transactions contemplated by the Merger Agreement; and

     - that includes appropriate financing commitments, or includes proposed
       financing commitments that are likely to be obtained on a timely basis in
       the good faith determination of the Special Committee after consultation
       with its financial advisors.

     The Company has also agreed to notify Medtronic promptly of any proposal or
inquiry relating to any acquisition proposal, including the identity of each
party making the acquisition proposal, and to provide reasonably detailed
information regarding the proposed terms of the acquisition proposal and the
information requested to be provided.

   23

PAYMENT OF FEES UPON TERMINATION EVENTS
(See Page 58)

     The Company must pay Medtronic a termination fee of $108 million if
Medtronic terminates the Merger Agreement because (a) the Board of Directors
withdraws or modifies in any respect adverse to Medtronic or the merger
subsidiary its recommendation of the Merger, (b) the Board of Directors
recommends to the stockholders any other acquisition proposal or has resolved or
announced its intention to do so or (c) a tender offer or exchange offer for 50%
or more of the outstanding shares of the Company common stock is announced or
commenced and either the Board of Directors recommends acceptance of the offer
or fails to recommend against it within 10 business days of when it commences.

     In addition, the Company must pay the termination fee if two sets of
conditions arise:

     - the Company or Medtronic has terminated the Merger Agreement because the
       Merger was not consummated within the time period specified in the Merger
       Agreement and described above, or the Company materially breached its
       obligations with respect to other acquisition proposals described above,
       or the stockholders of the Company failed to vote to adopt the Merger
       Agreement; and

     - another acquisition proposal has been made public and remains pending at
       the time of the termination of the Merger Agreement or the Special
       Meeting and, within 12 months after termination of the Merger Agreement,
       the Company enters into a definitive agreement with respect to another
       acquisition proposal or the transaction contemplated by another
       acquisition proposal is consummated.

     The Company also has to pay the termination fee if the Merger Agreement is
terminated by us as permitted by the Merger Agreement so that we may enter into
a binding written agreement regarding a superior proposal.

     In addition, if the Company does not pay the termination fee to Medtronic
when it becomes due, the Company must pay any costs and expenses incurred by
Medtronic in collecting the termination fee, including any legal fees and
expenses, and we must also pay interest on the amount of the termination fee
that is not paid when it becomes due. Medtronic must pay our costs and expenses,
including legal fees and expenses, if Medtronic files a lawsuit or takes other
legal action against us to collect the termination fee and does not prevail.

AMENDING, MODIFYING OR WAIVING TERMS OF THE MERGER AGREEMENT
(See Page 58)

     Any provision of the Merger Agreement may be amended, modified or waived by
the parties to the Merger Agreement prior to the closing date of the proposed
Merger. However, after the Merger Agreement is adopted by our stockholders, it
cannot be amended except in accordance with applicable law.

FEDERAL AND OTHER REGULATORY MATTERS

(See Pages 43 and 44)



     The HSR Act requires the Company and Medtronic to give information to the
Antitrust Division of the United States Department of Justice and the United
States Federal Trade Commission. After providing such information, a 30-day
waiting period must expire or be terminated before the Merger can be completed.
The waiting period may be extended by requests for additional information by the
Department of Justice or the Federal Trade Commission. The Company and Medtronic
made the required filings with the Department of Justice and the Federal Trade
Commission on June 28, 2001, and on Friday July 13, 2001, the waiting period was
terminated prior to its normal expiration date by the United States Federal
Trade Commission. The Company and Medtronic also will comply with the
requirements of all applicable foreign merger laws. We cannot predict whether we
will obtain all required regulatory approvals for the Merger, or whether any
approvals will include conditions that may be detrimental to Medtronic or the
Company.

LITIGATION RELATING TO THE MERGER
(See Page 43)

     As a result of the proposed Merger, the Company and its directors have been
named as defendants in a class action lawsuit filed on May 30, 2001 in the Court
of Chancery of the State of Delaware in and for New Castle County. The complaint
alleges that the $48 cash price per share to be paid to stockholders in
connection with the proposed Merger is inadequate and that the Company's
directors violated their fiduciary obligations in negotiating and approving the
Merger Agreement. In addition, the plaintiffs allege that the proposed Merger
was coupled with the sale of Medical Research Group in order to confer
substantial special benefits upon Alfred E. Mann and his affiliates at the
expense of a proper process to maximize value from the Merger. The complaint
seeks various remedies including injunctive relief that would, if granted,
prevent the completion of the Merger. The Company believes that these
allegations are without merit, and intends to vigorously defend this action.


     In addition, the Company and its directors have been named in a class
action lawsuit filed on June 6, 2001 in the Superior Court of the State of
California in and for the County of Los Angeles. The plaintiffs purport to
represent a class of stockholders of the Company asserting a claim related to
the Merger and in connection with an alleged violation of the fiduciary duties
owed by the Company and its directors to the Company's stockholders. The
complaint seeks preliminary and permanent injunctive relief that would, if
granted, prevent the completion of the Merger. The Company and its directors
have filed a motion to stay the California action, which is set for hearing on
August 13, 2001. The Company believes that these allegations are without merit,
and intends to vigorously defend this action.


PRICE OF COMMON STOCK
(See Page 60)

     The Company common stock is listed on the Nasdaq National Market under the
symbol "MNMD." On May 29, 2001, the last trading day before the public
announcement of the execution of the Merger Agreement, shares of Company common
stock closed at $44 per share. During the period from January 1, 2001 through
May 29, 2001, the high and low sale prices for shares of Company common stock on
the Nasdaq National Market were $45.75 and $25.00, respectively.

                              RECENT DEVELOPMENTS


     On July 18, 2001, we announced our results of operations for the fiscal
quarter ended June 29, 2001 and the six-month period then ended. For the
quarter, our net sales were $96.3 million and our net income (before
Merger-related expenses) was $9.4 million, or $0.14 per share on a diluted
basis. This represents a 38.76% increase in net sales as compared to $69.4
million for the comparable period in 2000, a 9.0% increase in net income as
compared to $8.6 million for the comparable period in 2000 and a 9.0% increase
in diluted earnings per share as compared to $0.13 for the comparable period in
2000. Including the effect of Merger-related expenses, net income was $4.2
million and diluted earnings per share were $0.06 for the quarter.



     For the six-month period ended June 29, 2001, our net sales were $176.3
million, our net income was $19.2 million and our diluted income per share was
$0.29. This represents a 35.9% increase in net sales as compared to $129.7
million for the comparable six-month period in 2000, a 28.8% increase in net
income as compared to $14.9 million for the comparable six-month period in 2000
and a 32% increase in diluted earnings per share as compared to $0.22 for the
comparable six-month period in 2000. Net income and diluted earnings for the
first six months of fiscal 2001 were $14.0 million and $0.21, respectively,
after giving effect to Merger-related expenses. Financial results for the
six-month period ended June 29, 2001 also include non-operating capital gains in
the first quarter of 2001 of $4.9 million, with an after-tax effect of $3.4
million.

                              THE SPECIAL MEETING

DATE; TIME; PLACE AND RECORD DATE OF THE SPECIAL MEETING


     The special meeting will be held on Wednesday, August 22, 2001 beginning at
10:00 a.m. (PDT), at the Warner Center Marriott, Grand Ballroom, 21850 Oxnard
Street, Woodland Hills, California 91367. The accompanying proxy is being
solicited by our Board of Directors and is to be voted at the special meeting or
any adjournment(s) or postponement(s) of the special meeting. The holders of
record of our common stock as of the close of business on July 16, 2001, the
record date for the special meeting, are entitled to receive notice of, and to
vote at, the special meeting. On the record date, there were 64,833,274 shares
of Company common stock outstanding. No other voting securities of the Company
are outstanding.


PURPOSE


     At the special meeting, you will be asked to consider and vote upon the
adoption of the Merger Agreement, which provides for the Merger of the merger
subsidiary with and into the Company, with the Company surviving the Merger as a
wholly-owned subsidiary of Medtronic. You will also be asked to vote on the
proposal to adjourn the special meeting, if needed, to permit the solicitation
of additional proxies to adopt the Merger Agreement. In the Merger, each issued
and outstanding share of Company common stock automatically will be canceled and
converted into the right to receive $48 per share in cash, without interest and
minus any required withholding for tax, with the following exceptions:


     - shares owned by the Company, Medtronic, the merger subsidiary, or any
       other wholly-owned subsidiary of the Company or Medtronic automatically
       will be canceled in the Merger without any payment; and

     - shares held by Company stockholders who properly perfect their appraisal
       rights under Delaware law will be subject to appraisal to determine the
       "fair value" of those shares in accordance with Delaware law.


     We do not expect to ask you to vote on any other matters at the special
meeting. However, if any other matters are properly presented at the special
meeting for consideration, the persons appointed as proxies will have discretion
to vote on these matters in accordance with his or her best judgment. These
matters may include an adjournment or postponement of the special meeting from
time to time if our board so determines. If any adjournment or postponement is
made and the adjournment proposal has been approved, we may solicit additional
proxies during the adjournment period.


VOTING INFORMATION


     Each outstanding share of Company common stock is entitled to one vote. The
presence, in person or by proxy, of the holders of a majority of the outstanding
shares of Company common stock entitled to vote at the special meeting is
necessary to constitute a quorum for the transaction of business at the special
meeting or any adjournment(s) or postponement(s) of the special meeting.
Abstentions are counted for purposes of determining whether a quorum exists at
the special meeting. The affirmative vote of the holders of a majority of the
outstanding shares of Company common stock is required to adopt the Merger
Agreement. Assuming a quorum is present, the affirmative vote of a majority of
the shares of Company common stock present in person or represented by proxy at
the special meeting is necessary to approve the adjournment proposal. Therefore,
proxies that reflect abstentions and proxies that are not returned will count as
a vote AGAINST adoption of the Merger Agreement.



     As of the record date for the special meeting, the Company's directors and
executive officers beneficially owned an aggregate of 13,925,178 of the
outstanding shares of Company common stock, representing approximately 21.48% of
the issued and outstanding shares of Company common stock as of the record date
for the special meeting. The Company's directors and executive officers have
indicated that they intend to vote all of the shares of Company common stock
beneficially owned by them FOR the adoption of the Merger Agreement.

Southern California have executed agreements to facilitate the Merger. These
agreements provide that the signatories must vote their shares of Company common
stock in favor of the approval, consent and ratification of the Merger Agreement
and the Merger and against any proposal or action that could impede, interfere
with, frustrate, nullify or discourage the Merger, could facilitate the
acquisition of the Company by a party other than Medtronic or could result in
any of the conditions to the obligations of the Company under the Merger
Agreement not being fulfilled. These agreements do not limit Mr. Mann's ability
to act consistently with his fiduciary obligations in such capacity as an
officer and director of the Company. The number of shares of MiniMed common
stock held by persons signing these agreements constitutes approximately 27% of
the number of shares of Company common stock outstanding.


     Brokers who hold shares in street name for customers have authority to vote
on "routine" proposals when they have not received instructions from beneficial
owners. However, absent specific instructions from the beneficial owner of the
shares, brokers are not allowed to exercise their voting discretion with respect
to the adoption and approval of non-routine matters, such as the Merger proposal
that will be voted on at the special meeting. Abstentions and properly executed
broker non-votes will be treated as shares that are present and entitled to vote
at the special meeting for purposes of determining whether a quorum exists, but
will have the same effect as votes AGAINST the adoption of the Merger Agreement.

SOLICITATION; REVOCATION AND USE OF PROXIES

     Proxies are being solicited by and on behalf of the Company's Board of
Directors. We will pay the costs of soliciting proxies from our stockholders as
well as all mailing and SEC filing fees incurred by us in connection with this
proxy statement. The Company has engaged the services of Morrow & Co., Inc. to
solicit proxies and to assist in the distribution of proxy materials. In
connection with its retention by the Company, Morrow & Co. has agreed to provide
consulting and analytic services and provide solicitation services with respect
to banks, brokers, institutional investors and individual stockholders. The
Company has agreed to pay Morrow & Co. a fee of $6,500 in addition to a fee for
any calls made by Morrow & Co. to Company stockholders. The Company also has
agreed to reimburse Morrow & Co. for all reasonable out-of-pocket expenses and
disbursements, and to indemnify Morrow & Co. against certain liabilities and
expenses under the federal securities laws. In addition to the solicitation of
proxies by mail, some of our directors, officers and employees may solicit
proxies by telephone, facsimile and personal contact, without separate
compensation for those activities. Copies of solicitation materials will be
furnished to fiduciaries, custodians and brokerage houses for forwarding to
beneficial owners of common stock, and these persons will be reimbursed for
their reasonable out-of-pocket expenses.

     You may revoke your proxy at any time before it is voted at the special
meeting. If you are a record holder, you may revoke your proxy in one of three
ways:

     - Prior to the special meeting, you can sign a written notice of your
       intent to revoke your proxy and deliver it to the Company at: MiniMed
       Inc., 18000 Devonshire Street, Northridge California 91325, Attention:
       Eric S. Kentor, Secretary. The notice of revocation must be received by
       the Company's Secretary before the vote is taken at the special meeting;

     - You can sign another proxy card with a later date and deliver it to the
       Secretary of the Company at or before the special meeting; or

     - You can attend the special meeting and vote your shares in person.

     If you choose to revoke your original proxy by attending the special
meeting and voting in person, you must actually vote in person at the special
meeting. IF YOU ATTEND THE SPECIAL MEETING BUT DO NOT ACTUALLY VOTE, YOUR
ORIGINAL PROXY WILL NOT BE REVOKED SOLELY BECAUSE YOU ATTENDED THE SPECIAL
MEETING IN PERSON.

     Any written notice of revocation or subsequent proxy should be sent to the
Secretary of the Company at the address listed above, or hand delivered to the
Secretary of the Company before the vote is taken at
                                        19

the special meeting. All valid proxies will be voted at the special meeting in
accordance with the instructions given by the record holder. If no instructions
are given, the shares represented by the proxy will be voted at the special
meeting for adoption of the Merger Agreement and, if additional votes are
necessary to adopt the Merger Agreement, for the adjournment proposal.


     If you hold your shares in "street name" and have instructed a broker to
vote your shares and you wish to change your vote, you must follow the
directions received from the broker as to how to change your vote. If you hold
your shares in "street name" and wish to vote your shares at the special
meeting, you must first obtain a legal proxy from your broker.


     Stockholders who do not vote in favor of or consent in writing to the
adoption of the Merger Agreement and the transactions contemplated by the Merger
Agreement, who submit a timely written demand for appraisal and who otherwise
comply with the applicable statutory procedures of the General Corporation Law
of the State of Delaware, will be entitled to seek appraisal of the "fair value"
of their common stock under Section 262 of the General Corporation Law of the
State of Delaware. The requirements for seeking and perfecting appraisal rights
under Delaware law are summarized in "SUMMARY -- Appraisal Rights" and "SPECIAL
FACTORS -- Appraisal Rights." The complete text of Section 262 of the General
Corporation Law of the State of Delaware, which specifies when and how a
stockholder may seek and perfect appraisal rights under Delaware law, is
attached as Appendix D to this proxy statement.


     Please do not send in your stock certificates at this time. If the Merger
is completed, we will send you instructions regarding how to exchange your stock
certificates for the $48 per share cash payment (without interest and minus any
required withholding for tax) to be paid pursuant to the Merger.

                                SPECIAL FACTORS

RELATIONSHIP WITH MEDICAL RESEARCH GROUP


     Concurrently with the execution and delivery of the Merger Agreement,
Medtronic also entered into a separate merger agreement with Medical Research
Group that provides for Medtronic to acquire Medical Research Group for an
aggregate payment ranging between approximately $428 million in cash and
approximately $416 million in Medtronic common stock, depending on whether and
how many Medical Research Group stockholders elect to receive Medtronic common
stock in lieu of cash and after deducting amounts paid to Medical Research Group
upon exercise of outstanding options. Alfred E. Mann, is the founder, Executive
Chairman and a significant stockholder of the Company and also serves as Medical
Research Group's Chairman. Mr. Mann and a corporation wholly-owned by him
together own approximately 32% of the outstanding shares of Medical Research
Group. In addition, the Alfred Mann Foundation, a non-profit research
organization established by Mr. Mann, owns approximately 7.6%, the Alfred E.
Mann Institute for Biomedical Engineering at the University of Southern
California, a non-profit medical research organization funded with an endowment
from Mr. Mann, owns an additional 11.2% and the University of Southern
California holds an additional 11.2% contributed by Mr. Mann and intended to be
transferred to a non-profit institute to be established at one or more different
academic institutions.



     Medical Research Group was founded by Mr. Mann to develop an implantable
long-term glucose sensor to monitor glucose levels of patients with diabetes.
The technology for the long-term glucose sensor is based upon technology
originally licensed from the University of California and from the Alfred Mann
Foundation by predecessors of Medical Research Group. Mr. Mann's initial 100%
beneficial ownership of the outstanding shares of Medical Research Group has
been diluted over time as a result of the transfers by Mr. Mann to the
organizations identified in the preceding paragraph, a 1998 private placement of
stock to outside investors, and the February 2001 investment by the Company
referred to below.


     In September 1998, the Company sold assets and transferred technology
relating to its implantable pump program to Medical Research Group and entered
into a series of related transactions. As part of these transactions, the
Company acquired an option to purchase for $30 million the worldwide, exclusive
marketing rights to the long-term glucose sensor being developed by Medical
Research Group and retained exclusive marketing rights to the implantable pump
product line for diabetes and certain other medical conditions. Under these
initial arrangements, the Company was obligated to make mandatory purchases of
implantable pumps from Medical Research Group through 2001 and additional
purchases of these products in subsequent periods to retain the exclusivity of
its marketing rights to the implantable pump.

     In February 2001, the Company restructured its agreements with Medical
Research Group and exercised its option for the worldwide marketing rights to
Medical Research Group's long-term glucose sensor. Concurrently with the
restructured operating agreements with Medical Research Group, the Company made
a $30 million equity investment in Medical Research Group, thereby acquiring
approximately 8% of its outstanding shares. This price implied a pre-investment
value for Medical Research Group of approximately $345 million at that time, not
including any premium that normally would be expected to be paid in a sale of
all of Medical Research Group. Additionally, Medical Research Group waived prior
minimum purchase commitments, and the Company agreed to make mandatory minimum
purchases of implantable pump units from Medical Research Group aggregating
approximately $17,100,000 over the next four years. In these negotiations, the
Company was represented by an independent committee of the Board of Directors,
which retained U.S. Bancorp Piper Jaffray Inc. to render an opinion as to the
fairness, from a financial point of view, of that transaction to the Company. As
of December 29, 2000, the Company had accrued $3,285,000 related to implantable
pump purchase commitments in excess of expected usage during the four-year
period.

     In addition to maintaining these mandatory purchase commitments in order to
maintain its exclusive marketing rights with respect to implantable pumps, the
Company is required to pay license fees of $12.5 million to Medical Research
Group upon achievement of development milestones for future products for the
treatment of diabetes that are in the early stages of development. The Company
is also required to

                                        21
   30

pay additional fees of up to $12 million in periods subsequent to 2002, subject
to reduction of that amount to the extent that the Company purchases implantable
pumps in excess of its minimum purchase requirements. If the Company fails to
satisfy the minimum purchase commitments in 2003 or 2004 or fails to make the
required license fee payment, Medical Research Group has the right to repurchase
all of the distribution rights for the implantable pump and the long-term
glucose sensor for $60 million or purchase the distribution rights to Medical
Research Group's next generation implantable pump for $7.5 million. In addition,
Medical Research Group has the right to terminate the exclusive nature of the
Company's distribution rights if the Company fails to meet continuing minimum
purchase requirements after 2004. Medical Research Group has agreed to
supplement the Company's funding of the development of the special insulin for
the implantable pump system and to fund a greater portion of the clinical trials
of the long-term glucose sensor. The Company has also agreed that its exclusive
marketing rights to the implantable pump will be limited to the treatment of
diabetes and not any other medical conditions.

BACKGROUND OF THE MERGER

     Since we went public in July 1995, companies have approached us from time
to time regarding possible strategic transactions, including the possibility of
another company acquiring us.

     In October 1998, our Board of Directors evaluated various private financing
sources of working capital. In this connection, Mr. Mann, our Executive
Chairman, contacted William George, Chairman of Medtronic. This contact led to
Medtronic's purchase from us of approximately 3% of the then outstanding Company
common stock for $30 million. Medtronic later sold that stock.

     During the fourth quarter of 1999, Medtronic representatives contacted Mr.
Mann and our investment banker, expressing an interest in a possible strategic
transaction with us. Preliminary discussions ensued. In these discussions,
Medtronic indicated its interest in concurrently acquiring Medical Research
Group. During April 2000, Medtronic asked to have more substantive discussions
with us regarding a possible strategic transaction. Medtronic conducted a due
diligence review of Medical Research Group and us during May 2000.

     On May 11, 2000, the Board of Directors held a special meeting at which Mr.
Mann reported on recent discussions with Medtronic regarding a possible
strategic transaction between the two companies, and Medtronic's potential
interest in a concurrent acquisition of Medical Research Group. The Board of
Directors then formed the Special Committee, composed of three directors, Thomas
R. Testman (as Chairman), William R. Grant and John C. Villforth. No member of
the Special Committee is or has been an employee of the Company, and no member
has any financial relationship with Mr. Mann or ownership or other interest in
Medical Research Group. The Special Committee was formed, in part, because Mr.
Mann is Medical Research Group's Chairman and has a substantial ownership
interest in Medical Research Group that could have created conflicts of interest
in any transaction involving both Medical Research Group and us. Mr. Mann did
not participate with other members of senior management in providing information
or advice to, or in connection with the deliberations of, the Special Committee,
except on a limited basis when requested to do so by the Special Committee.

     The Board of Directors gave the Special Committee broad authority,
including the authority to review, evaluate, respond to and negotiate a
transaction with Medtronic. The Board also gave the Special Committee similar
authority to explore and consider any other business combination proposals,
offers or expressions of interest we received during the Medtronic discussions
and negotiations.

     At the same Board meeting, independent legal counsel, who had been engaged
to advise the Special Committee in connection with the potential transaction,
gave a presentation on the fiduciary duties of our directors in the context of
such a transaction. Representatives from UBS Warburg reviewed with the Board
certain financial aspects of a possible transaction with Medtronic.

     On May 15, 2000, the Special Committee held a meeting at which its
independent counsel gave the Special Committee further legal guidance. The
Special Committee decided that it was appropriate to ask UBS Warburg, which was
initially retained as the Company's financial advisor, to also act as the
Special

                                        22
   31


Committee's financial advisor. Our senior management reported that they, UBS
Warburg, and legal counsel had begun a due diligence review of Medtronic.


     Throughout the period up to mid-June 2000, our senior management and UBS
Warburg had general discussions with representatives of Medtronic regarding the
possibility of a strategic transaction, including the potential structure and
terms of a transaction. Our senior management visited Medtronic's headquarters
in Minneapolis on May 30, 2000, to conduct due diligence on Medtronic and meet
with Medtronic's officers. During this period, the Special Committee met twice
to review with our senior management and UBS Warburg the potential structure
for, and to discuss other issues relating to, a transaction with Medtronic,
including potential issues relating to Medtronic's desire to accomplish a
concurrent acquisition of Medical Research Group, and a requirement that a
transaction be structured as a stock-for-stock merger that qualified for pooling
of interests accounting treatment. The Special Committee authorized continued
discussions with Medtronic.

     Despite these discussions, no agreement could be reached with Medtronic,
primarily because of the relative trading values of the two companies' stock
prices. As a result, in early July 2000, we mutually decided to terminate
discussions.

     At regular meetings on June 21 and July 12, 2000, the Board reviewed the
status of discussions with Medtronic, including the mutual decision to terminate
discussions.

     In January 2001, Medtronic representatives contacted us and expressed an
interest in resuming discussions relating to a possible strategic transaction
involving an exchange of its shares for our shares. Medtronic continued to
require the consummation of a strategic transaction with Medical Research Group
concurrently with a transaction with us.

     On January 25, 2001, at a regular meeting of the Board, Mr. Mann reported
that Medtronic had reinitiated discussions with us regarding the possibility of
a strategic stock-for-stock transaction. Our senior management reported that
such discussions were still preliminary in nature, but the parties were
exploring the possibility of such a transaction. The Board requested that senior
management report back if the discussions became more serious.

     On February 9, 2001, Mr. Mann reported at a special meeting of the Board
that he had received a letter dated February 2, 2001 from Medtronic expressing
an interest in a transaction involving Medical Research Group and us. The
proposal involved a stock transaction for separate but concurrent mergers of the
Company and Medical Research Group with Medtronic, based on a fixed exchange
ratio of one share of Medtronic common stock for each share of Company common
stock, to be allocated between the Company's stockholders and the Medical
Research Group stockholders. The letter did not specify any allocation of the
purchase price between the two companies, and Medtronic's proposal lacked
adequate details to determine the overall valuation implied, which could only be
clarified through further discussion and negotiation. Mr. Mann also noted that
two other large companies in the health care industry also had indicated an
interest in talking to us about a possible strategic stock-for-stock
transaction. As a result, the Board reconvened the Special Committee.

     At a February 12, 2001 meeting, the Special Committee discussed the status
of our preparation of a long-term strategic plan, the timing of the availability
of strategic information necessary for the Special Committee to evaluate our
alternatives fully, the status of discussions with other companies that had
expressed interest in considering a strategic stock-for-stock transaction with
us, and related matters. The Special Committee decided to continue to use UBS
Warburg as the Special Committee's primary financial advisor in discussions with
Medtronic and other companies that would be likely to have the resources and
interest in pursuing a strategic stock-for-stock transaction with us. Our senior
management and UBS Warburg reported on preliminary discussions with Medtronic
and the two other companies referred to above regarding a potential strategic
transaction with us. The Special Committee authorized our senior management and
UBS Warburg to continue these discussions, and to continue to identify companies
that might provide a good strategic fit for us and enable the Special Committee
to evaluate the value that might be available for our stockholders through a
strategic transaction.

                                        23
   32

     In February 2001, Salomon Smith Barney introduced a foreign company to us
that might be interested in a strategic stock-for-stock transaction with us. We
subsequently entered into an engagement letter with Salomon Smith Barney under
which it would provide certain services to us. See "SPECIAL FACTORS -- Interests
of the Company's Directors and Officers in the Merger."

     At meetings on February 22 and March 1, 2001, the Special Committee
received updates from our senior management and UBS Warburg on discussions with
Medtronic and other companies and the possible benefits and financial
implications of a potential strategic stock-for-stock transaction. The Special
Committee indicated that discussions with any company should be viewed as
exploratory and that it was still in the process of evaluating the strategic
opportunities available to us as an independent organization or in connection
with a strategic transaction with a third party.

     On March 15 and 16, 2001, the Board held its annual strategy and planning
meetings, during which the Board and senior management discussed in detail our
operational, financial, and strategic plans for the future and the various
possible benefits, risks and capital requirements of these plans. The Chairman
of the Special Committee gave a report on the status of discussions with
Medtronic and other companies. The Board approved the continuance of these
discussions. During these meetings, the Special Committee decided that it would
be appropriate to retain independent legal counsel for the Special Committee,
and subsequently retained O'Melveny & Myers LLP as its independent legal
counsel.


     On March 21, 2001, the Special Committee held a meeting to receive an
update on the status of discussions. Our senior management and UBS Warburg
indicated that active, but preliminary, discussions about a strategic
stock-for-stock transaction were taking place with four companies (including
Medtronic). With the exception of the one foreign-based company, the other
companies indicated that they would require that any transaction qualify for
pooling of interests accounting treatment. At the Special Committee's request,
our senior management reviewed our anticipated capital requirements in
connection with our strategic plan to assist the Special Committee in its
evaluation of possible strategic alternatives. Management indicated that for us
to accomplish our principal new projects and possible acquisitions that the
Board evaluated at its annual strategic meeting retreat on March 15 and 16,
2001, additional capital would have to be generated either from operations or
from financing transactions.


     At a March 28, 2001 meeting, O'Melveny & Myers gave the Special Committee
an overview of the relevant duties and responsibilities of the Special
Committee. UBS Warburg gave an update on the status of negotiations with the
four companies (including Medtronic) with which discussions were ongoing. Each
of these four companies had stated an interest in conducting a due diligence
review of Medical Research Group in light of the contractual relationship
between us and Medical Research Group. At the same meeting, our senior
management discussed accounting issues that might arise in a possible
transaction involving Medical Research Group, particularly as to whether Medical
Research Group would qualify for pooling of interests accounting treatment.

     At the March 28, 2001 meeting, the Special Committee also discussed the
implications of another company insisting on a concurrent transaction involving
Medical Research Group and us. The Special Committee believed that any potential
conflicts of interest would be better identified and evaluated by the Special
Committee if it and its advisors were kept aware of the status of those
discussions, but that the Special Committee and its advisors would not be
actively involved in the substantive aspects of a Medical Research Group
transaction. The Special Committee considered that it might play a role in
procedural issues if doing so was necessary or desirable to facilitate an
attractive transaction involving us. The Special Committee discussed that this
role might include assisting in connection with pooling of interests accounting
issues, since Medical Research Group's status in that regard could affect the
ability of a party to effect concurrent mergers with both of us. If an
attractive transaction involving us that was consistent with the Special
Committee's views about our appropriate strategic future could be facilitated on
a basis that was in the best interests of our stockholders, the Special
Committee concluded that it would explore and facilitate such a transaction even
if it involved Medical Research Group. However, the Special Committee believed
that efforts should be made to avoid direct linkage between any transaction
involving us and any transaction involving Medical Research Group.

     On April 5, 2001, the Special Committee held a meeting to receive a status
report. Our senior management reported on the status of the discussions with the
other companies regarding pooling of interests accounting issues. UBS Warburg
reported that each of the interested companies was completing its due diligence
investigations and internal review processes. The foreign company suggested an
exchange of shares for our shares with a value of up to approximately $40 per
share. In light of the status of discussions with other companies, UBS Warburg
was instructed to inform the foreign company that this valuation was not
attractive, but that it was welcome to submit a higher proposal.

     At an April 10, 2001 meeting, the Special Committee discussed the status of
the other companies' evaluation of pooling of interests accounting issues
involving Medical Research Group. Since the remaining three interested companies
seemed to be at roughly comparable stages in terms of their due diligence and
internal review processes, the Special Committee decided that it would be
desirable to attempt to bring discussions to fruition soon.


     On April 10, 2001, Medtronic sent us a non-binding letter indicating that
it would be interested in merging with us in a stock-for-stock transaction with
an exchange ratio of .87 of a share of Medtronic stock for each of our shares,
which would equate to a per share value, based upon the then current trading
price of Medtronic's common stock, of approximately $36.50 for each of our
shares. As had been the case in the past, this proposal was linked to
Medtronic's concurrent acquisition of Medical Research Group for Medtronic
common stock in a transaction that would qualify for pooling of interests
accounting treatment. The Special Committee instructed UBS Warburg to inform
Medtronic that the per share value of the Company's shares reflected in its
proposal was not acceptable.


     On April 19, 2001, the Special Committee held a meeting to receive a status
report. At the request of the Special Committee, a representative of Deloitte &
Touche, our independent accounting firm, gave a presentation about pooling of
interests accounting issues that might arise in a transaction involving Medical
Research Group. UBS Warburg confirmed that the foreign company had indicated
that the foreign company was unlikely to increase its range of value for us. UBS
Warburg also noted that, in accordance with the instructions of the Special
Committee, it had informed Medtronic that its proposal was not acceptable. One
of the other companies had indicated that it needed additional time to evaluate
the information it had obtained in due diligence. The remaining company had
indicated that, in light of our high market valuation relative to earnings, it
did not believe that it would be in a position to propose an exchange ratio that
would value our shares above the high $30s per share since it had not identified
substantial cost savings or operational synergies in a merger with us. The
Special Committee discussed strategy and timing, and, in order to expedite the
process, authorized O'Melveny & Myers to prepare, with our senior management, a
form of merger agreement that might be proposed if any of the companies appeared
serious.

     At an April 27, 2001 Special Committee meeting, UBS Warburg told the
Special Committee that in a letter dated April 25, 2001 Medtronic had withdrawn
its earlier offer and that Medtronic indicated that it had done so because
Medtronic believed we had decided to change the potential acquisition process.
UBS Warburg then summarized recent discussions with the remaining interested
company, which had substantially completed its evaluation of due diligence
information. That company had expressed an interest in entering into a
simultaneous strategic combination with Medical Research Group and us, but was
concerned about whether it would be able to obtain pooling of interests
accounting treatment with respect to its potential acquisition of Medical
Research Group. That company also said that it might be interested in merging
with us without acquiring Medical Research Group if it could not obtain pooling
of interests accounting treatment, but that it wanted to evaluate possible
modifications to the agreement between Medical Research Group and us. The
Special Committee then discussed timing and strategic issues relating to these
developments.

     On May 4, 2001, the Special Committee held a meeting at which UBS Warburg
informed the Special Committee that Medtronic had indicated that it remained
interested in pursuing a transaction with us, notwithstanding the formal
withdrawal of its offer. The company other than Medtronic that remained in
active discussions with us at this point concluded that it did not want to
acquire Medical Research

                                        25
   34

Group because of concerns about its ability to obtain pooling of interests
accounting treatment for that acquisition, but that it was continuing to
evaluate issues relating to our contract with Medical Research Group. The
Special Committee reaffirmed its instructions to its advisors and our senior
management to continue to explore the possibility of pursuing a strategic
combination and to attempt to resolve related issues. The Special Committee
authorized the distribution of a draft merger agreement, prepared at the Special
Committee's request, to Medtronic and the other interested company. The Special
Committee also discussed the need to conduct due diligence with respect to the
two companies.

     A draft merger agreement was delivered to Medtronic on May 9, 2001 and to
the other company on May 10, 2001.

     On May 10, 2001, the Special Committee and our senior management again
discussed the pooling of interests accounting issue involving Medical Research
Group. The Special Committee directed UBS Warburg to inform Medtronic and the
other company that proposals and written comments on the draft merger agreement
should be submitted within two weeks.

     On May 10, 2001, at the request of the Special Committee, our senior
management instructed U.S. Bancorp Piper Jaffray that it should commence work to
be in a position to render an opinion as to the financial fairness of the
transactions under discussion if requested by the Special Committee. In
connection with its work for a different special committee of the Board in early
2001 relating to the transaction between us and Medical Research Group described
in "Relationship With Medical Research Group" above, a portion of U.S. Bancorp
Piper Jaffray's fees was deferred, and U.S. Bancorp Piper Jaffray was entitled
to the deferred fee of $1.4 million if we acquired greater than 50% of the
equity or assets of Medical Research Group or if a transaction such as the
Merger were consummated prior to our acquisition of at least 50% of the assets
or equity of Medical Research Group. Under the terms of the prior engagement,
U.S. Bancorp Piper Jaffray had the option to act as a financial advisor and to
render a fairness opinion at our request in connection with any transaction such
as the Merger if the $1.4 million deferred fee had not been paid. The Special
Committee concluded that it would be desirable to obtain such a second opinion.

     On May 14, 2001, at the request of the Special Committee, our chief
financial officer distributed to the Special Committee recent analyst research
reports and other information about us, and recent analyst research reports on
the other company and Medtronic, since they appeared to be the two companies
that continued to be primarily interested in a possible transaction with us.

     At a May 17, 2001 meeting, the Special Committee was updated on the status
of discussions and due diligence items. The Special Committee and our senior
management discussed due diligence issues regarding the regulatory and
litigation status of the company other than Medtronic. At the Special
Committee's request, Salomon Smith Barney joined the meeting to review with the
Special Committee certain background financial and strategic information
relating to Medtronic and the other company. Salomon Smith Barney was not asked
to, and did not, render any specific advice or opinion with respect to either
company or a potential transaction with either of them. The Special Committee
and our senior management also discussed the benefits and disadvantages of
remaining independent. The Special Committee concluded that there was a
possibility that a transaction with a third party on economically favorable
terms would outweigh the advantages of remaining independent and would be in the
best interests of the Company's stockholders. Therefore, the Special Committee
directed our senior management and the Special Committee's advisors to continue
discussions with interested companies with a view toward improving the proposed
terms and bringing matters to closure.

     On May 22, 2001, the Special Committee held a meeting with our senior
management and the Special Committee's advisors to discuss a written proposal
(together with comments on the draft merger agreement) received from the company
other than Medtronic. That letter proposed a stock-for-stock transaction with an
exchange ratio with a value (based on the then-current price of such company's
shares) of approximately $46 for each of our shares. The Special Committee
identified several terms of that proposal that were objectionable and discussed
how to instruct our senior management and the Special Committee's advisors to
negotiate those terms. Those terms included the method of computing an
                                        26
   35

appropriate exchange ratio, the extent of provisions designed to discourage
competing higher offers after the execution of the proposed merger agreement,
and a requirement that, as a condition to face to face negotiations, we
terminate discussions with other companies and negotiate with that company
exclusively until June 21, 2001. The Special Committee instructed our senior
management and the Special Committee's advisors to refuse the other company's
request for exclusivity before pursuing negotiations regarding the other terms.
Negotiations with the other company ensued, and the other company dropped its
exclusivity requirement on May 23, 2001. The Special Committee also identified
areas that we would need to investigate when we performed due diligence on the
other company.

     On May 23, 2001, Mr. Mann and Mr. Gregg met with senior executives of the
other company and discussed possible structures of a proposed transaction,
operational issues, economic considerations, and related terms.

     On May 24, 2001, our senior management and the Special Committee's advisors
met with representatives of the other company at its offices to negotiate a
possible merger agreement. The parties engaged in extensive negotiations over a
two-day period and, while substantial progress was made on many points, no
definitive agreement was reached. Among other things, the other company would
not agree to our negotiating team's attempts to revise the proposed method of
computing the proposed exchange ratio or to add provisions to the draft merger
agreement that would protect the proposed $46 per share value for our
stockholders if the other company's stock declined before closing.

     In the evening of May 24, 2001, the Special Committee held a meeting at
which our senior management and the Special Committee's advisors discussed the
status of negotiations with the other company. UBS Warburg informed the Special
Committee that Medtronic had submitted a new written proposal dated May 24,
2001, in which Medtronic proposed acquiring us in a merger involving the payment
by Medtronic to our stockholders of $48 cash per share, and acquiring Medical
Research Group concurrently. The Special Committee deliberated about the
implications of this proposal on the status of discussions with the other
company and issues associated with a cash, instead of a stock, transaction. At
the request of the Special Committee, Mr. Mann joined the meeting to receive an
update about the recent developments. Mr. Mann indicated that even though the
proposed new cash transaction between Medtronic and us might have significantly
adverse tax consequences for him personally, he would support whatever decision
the Special Committee and our senior management believed was in the best
interests of our stockholders. The Special Committee discussed strategy with our
senior management and the Special Committee's advisors, including whether the
financial terms of the new Medtronic proposal could be improved. UBS Warburg was
authorized to explore this possibility. At the end of the meeting, the Special
Committee held a separate session with O'Melveny & Myers during which the
implications of the proposed cash transaction, and the duties and
responsibilities of the Special Committee in that context, were discussed.

     On May 25, 2001, our negotiating team continued its discussions with the
company other than Medtronic. The price of the other company's shares, upon
which it had based its proposed exchange ratio, had declined slightly from its
recent high, and would have valued our shares at approximately $44.15 per share
at the close of trading on May 25. Significant open issues remained with respect
to the merger agreement proposed by the other company, including provisions that
were designed to thwart competing higher offers and various other provisions.
Counsel for the other company was to send a revised draft of the proposed merger
agreement to our negotiating team on May 26, reflecting the negotiations to
date. The parties discussed being available for negotiations over the ensuing
weekend. In the afternoon of May 25, after our negotiating team had left the
other company's offices, the other company called Mr. Terrance H. Gregg, a
director and executive officer of the Company, to advise him that it was
terminating negotiations because, among other reasons, its stock price had
declined and it did not believe that a strategic transaction was viable at such
levels. The other company left open the possibility of further discussions if
future changes in the relative trading prices of its shares and our shares made
a transaction feasible.

                                        27
   36

     We received a draft merger agreement from Medtronic on May 26, 2001,
reflecting its May 24, 2001 proposal. Our negotiating team viewed the terms of
this proposed draft to be a reasonable basis for moving forward with
negotiations.

     Commencing on May 27, 2001, our senior management and the Special
Committee's advisors held negotiations by telephone and exchanged documents with
Medtronic's management and advisors. These negotiations continued until the
announcement of the Merger on May 30, 2001. Informal discussions were held
during this period between members of our negotiating team and the Special
Committee's Chairman, and by him with the other members of the Special
Committee.

     Medtronic held concurrent but separate negotiations with Medical Research
Group and its counsel. At the request of the Special Committee, UBS Warburg kept
the Special Committee apprised of those negotiations, and O'Melveny & Myers
reviewed various drafts of the related agreements, in order to keep the Special
Committee informed as to material developments that might affect the timing or
completion of a transaction with Medtronic. During those negotiations, our
negotiating team became aware that the consideration to be paid for Medical
Research Group would be modified to include an election allowing Medical
Research Group stockholders to receive some or all of the payment in shares of
Medtronic common stock. To the extent Medical Research Group stockholders
elected stock, this would enable Medical Research Group's stockholders to defer
some of the tax payable on their shares. UBS Warburg was advised by
representatives of Medtronic that, while Medtronic was receptive to discussing
alternative payment structures in a merger with us, in light of the large number
of shares that Medtronic would have to issue pursuant to a merger with us,
Medtronic was not willing to issue the amount of stock necessary to consummate a
tax-free reorganization.

     The Special Committee had identified several provisions of Medtronic's
proposal that the Special Committee objected to, including (a) a provision that
the closing of the proposed merger was conditioned on the acquisition of Medical
Research Group by Medtronic and that if the Medical Research Group transaction
failed to close for any reason a merger with us would not close, (b) Medtronic's
request that its obligation to close a merger with us would be subject to its
raising financing, and (c) various provisions designed to discourage competing
higher offers.

     On May 28, 2001, the Special Committee held a meeting to continue its
discussions about the Medtronic proposal and related matters. At the request of
the Special Committee, U.S. Bancorp Piper Jaffray gave an overview of the scope
of the fairness opinion that U.S. Bancorp Piper Jaffray would be prepared to
deliver regarding the proposed Medtronic transaction, subject to final review of
documentation. In addition, in light of U.S. Bancorp Piper Jaffray's financial
evaluation of Medical Research Group in connection with its advice in February
2001 to a different special committee of the Board, at the request of the
Chairman of the Special Committee, U.S. Bancorp Piper Jaffray discussed
generally with the Special Committee various financial factors that could be
evaluated by the Special Committee in deciding whether there was a need for
further inquiry by the Special Committee into aspects of the Medical Research
Group transaction other than those the Special Committee was already
considering. U.S. Bancorp Piper Jaffray was not asked to, and did not, render
any specific advice or opinion with respect to Medical Research Group or a
potential transaction with it. The Special Committee noted that our February
2001 purchase of an 8% minority interest in Medical Research Group had implied a
pre-investment value for Medical Research Group of approximately $345 million at
that time, not including any premium that normally would be expected to be paid
in a sale of all of Medical Research Group. In connection with that transaction
and a subsequent payment by us under our contract with Medical Research Group,
Medical Research Group had received an additional $60 million in cash, and there
had been progress in the development of its products since our February 2001
investment. The Special Committee concluded that, based on its own substantial
knowledge of Medical Research Group and its business, and the discussion at this
meeting, it was satisfied that the proposed value attributed to Medical Research
Group by Medtronic did not make it necessary to pursue further financial
analysis of the Medical Research Group transaction. However, the Special
Committee instructed our negotiating team to attempt to be kept apprised of that
transaction and alert the Special Committee if issues arose that might affect a
transaction between Medtronic and us. The Special Committee then discussed with
our senior
                                        28
   37

management and the Special Committee's advisors the major unresolved issues with
Medtronic. The Special Committee again expressed its concern about Medtronic's
continued insistence on linking a Medical Research Group transaction to a
transaction with us and instructed the negotiators to resist that provision in
particular. The negotiating team reported that several times during the course
of negotiations, Medtronic representatives stated that Medtronic's willingness
to pay $48 for each of our shares was predicated on Medtronic being able to
acquire both companies at the same time and that it would have to revisit the
pricing if it could not be reasonably assured that it could do so. By this point
in the negotiations, Medtronic had withdrawn its request that its obligations to
close a merger with us be subject to its raising financing.

     On May 28, 2001, O'Melveny & Myers delivered a memorandum to the Special
Committee summarizing the principal terms of the proposed Medtronic merger
agreement and reflecting various agreements reached on certain points, including
the elimination or substantial modification of many of the objectionable points.

     In the morning of May 29, 2001, the Special Committee held a meeting at
which the Special Committee discussed with our senior management and the Special
Committee's advisors the issues in the proposed Medtronic merger agreement that
remained unresolved at that time. U.S. Bancorp Piper Jaffray gave a presentation
to the Special Committee, and indicated that, subject to satisfactory resolution
of the remaining issues and review of final documents, and based upon and
subject to certain limitations, assumptions and qualifications to be set forth
in its written opinion, U.S. Bancorp Piper Jaffray was prepared to opine that,
as of May 29, 2001, the $48 cash price per share proposed to be paid by
Medtronic was fair to our stockholders from a financial point of view. After
U.S. Bancorp Piper Jaffray's presentation, UBS Warburg reviewed with the Special
Committee its financial analysis of the $48 cash price per share and also
indicated that it would be prepared to render its opinion, subject to
satisfactory resolution of remaining issues and review of final documents.

     In the afternoon of May 29, 2001, the Special Committee, having reviewed
the proposed merger agreement and the memorandum from O'Melveny & Myers, held a
meeting at which it discussed with our senior management and advisors the
resolution of the issues that they had reached with Medtronic regarding the
proposed merger agreement and the issues that remained open. The Special
Committee concluded that it was prepared to make a recommendation to approve the
proposed merger if the issue relating to the linkage to the transaction with
Medical Research Group could be resolved. The Special Committee gave guidance to
the negotiating team as to the type of conditions the Special Committee would be
willing to accept if the objectionable provision could not be wholly eliminated.
After full consideration and discussion, the Special Committee concluded that
the $48 cash price per share proposed to be paid by Medtronic was likely to be
the highest price reasonably obtainable and that every reasonable effort should
be made to conclude negotiations as promptly as possible.


     On May 29, 2001, subject to satisfactory resolution of the remaining open
issue regarding the linkage to the transaction with Medical Research Group, in
conjunction with a meeting of the Board, the Special Committee unanimously
approved the Merger Agreement and recommended that the Board approve the Merger
Agreement. The Board then held a meeting at which the Board (a) received the
Special Committee's report and recommendation, (b) received the respective oral
opinions from UBS Warburg and U.S. Bancorp Piper Jaffray as to the fairness,
from a financial point of view and as of the date of their respective opinions,
and based on and subject to the limitations, assumptions and qualifications
stated in their respective opinions, of the $48 per share cash consideration to
be received in the Merger by holders of Company common stock, and (c) received
recommendations from our senior management and advice from our General Counsel
and O'Melveny & Myers. Subject to resolution of the remaining issue, the Board
concluded that the Merger was advisable and in the best interests of our
stockholders and unanimously approved the Merger, the Merger Agreement, and the
transactions contemplated by the Merger Agreement.


                                        29
   38

     On May 29, 2001, the Medtronic board of directors approved the Merger,
subject to final negotiations by senior management, and authorized Medtronic's
officers to undertake all acts necessary or advisable to effect the Merger.

     Early in the morning of May 30, 2001, the negotiators reached a resolution
of the issue with respect to the linkage to the transaction with Medical
Research Group to the proposed merger between Medtronic and us. Our merger,
relative to Medical Research Group's status, would be affected only by
Medtronic's failure to receive Hart-Scott-Rodino antitrust approval to acquire
Medical Research Group (which all parties believed to be unlikely) and there
being no material adverse effect with respect to, or breach of representation
and warranty by, Medical Research Group that, when viewed together with us,
would have a material adverse effect on us and Medical Research Group considered
as a whole. UBS Warburg and U.S. Bancorp Piper Jaffray then delivered their
respective written opinions as described above.


     We then executed the Merger Agreement with respect to the Merger. Mr. Mann
and entities affiliated with him executed Agreements to Facilitate the Merger,
including voting in favor of it at our special meeting of stockholders. The
Alfred E. Mann Charitable Remainder Trust, the Alfred Mann Foundation, and the
Alfred E. Mann Biomedical Institute at the University of Southern California
subsequently executed Agreements to Facilitate the Merger. Mr. Gregg, Kevin
Sayer and David Morley also executed non-competition agreements as contemplated
by the Merger Agreement and Stephen A. Bowman subsequently executed a
non-competition agreement.


     On the morning of May 30, 2001, before the opening of the United States
stock markets, the Merger was publicly announced.


     The Company, Medtronic and the merger subsidiary entered into an amendment
and restatement of the Merger Agreement, dated as of June 19, 2001, which
amended and restated the Merger Agreement executed May 30, 2001 to provide that
any options to purchase Company common stock outstanding and not exercised at
the effective time of the Merger would be assumed by Medtronic and after the
Merger would be exercisable to purchase Medtronic common stock.


REASONS FOR THE MERGER

     The Company. The Special Committee and the Board have each unanimously
determined that the Merger is fair to and in the best interests of the Company
and our stockholders and have approved and declared the advisability of the
Merger Agreement.

     The following are the material factors the Special Committee considered in
reaching its conclusion:

     - The cash price of $48 per share to be paid pursuant to the Merger,
       including the fact that such amount represents a premium of 25.1% over
       the market price for our shares on January 25, 2001 (the date that the
       most recent discussions with Medtronic commenced), 39.2% over the average
       closing market price of our shares for the ninety trading days through
       May 29, 2001 (the day before the Merger was announced), and approximately
       9% over the closing market price on May 29, 2001 (the day before the
       announcement of the Merger Agreement).

     - The fact the cash price of $48 to be paid pursuant to the Merger is a
       fixed amount, compared to the uncertainties in a stock-for-stock
       transaction, and that in accepting a cash transaction our stockholders
       would not be subject to the risks associated with a decline in the
       trading price of shares to be exchanged, but would not receive any future
       benefits of any increase in the price of Medtronic common stock or our
       common stock.

     - The fact that a cash transaction, such as the Merger, would have
       immediate tax consequences to our stockholders rather than a deferral of
       tax liabilities that might have been available in a stock-for-stock
       exchange.

     - The current and prospective business environment in which we operate,
       including: economic, market, regulatory, and competitive conditions; the
       benefits, costs and risks inherent in our strategic plan, which
       contemplates significant growth through acquisitions and new product
       development and
                                        30
   39

       distribution; the risk of being a technology company with a narrow
       product line and a relatively high price earnings ratio; existing and
       potential increased competition from other companies challenging our
       market leadership role, and the prospect of substantially larger, better
       financed companies entering our markets; and the risk of not being able
       to maintain our management team if we remain independent.

     - Our strategic alternatives, including remaining a separate company and
       growing internally or through acquisitions or remaining a separate
       company while continuing to explore a merger or joint venture transaction
       with another party; the consolidation taking place among suppliers of
       medical devices and equipment, which suggested to the Special Committee
       that large companies will be better able to compete in these industries
       and that it is an attractive time for smaller companies (such as us) to
       consider alternatives to staying independent; and the significant
       challenges that we would face as an independent company if we did not
       proceed with the proposed Merger, including the effect of unpredictable
       and volatile equity and debt markets on our ability to raise capital.

     - The discussions and negotiations that took place with other companies
       that expressed interest in a possible merger or similar transaction with
       us.

     - The financial presentations, including the respective opinions of UBS
       Warburg and U.S. Bancorp Piper Jaffray as to the fairness, from a
       financial point of view and as of the date of their respective opinions,
       and based on and subject to the limitations, assumptions and
       qualifications stated in their respective opinions, of the $48 per share
       cash consideration to be received in the Merger by holders of Company
       common stock, as described below under "Opinion of UBS Warburg LLC" and
       "Opinion of U.S. Bancorp Piper Jaffray Inc."

     - Discussions with representatives of our senior management and independent
       accounting firm and the Special Committee's financial and legal advisors
       regarding the business, accounting, financial and legal aspects, and the
       terms and conditions, of the Merger and various other transactions
       considered.


     - The fact that we have an ability to respond to, and to accept, an
       unsolicited offer that is superior to the Merger, if failing to do so
       would be a breach of the Board's fiduciary responsibilities to our
       stockholders imposed by law, and the extent to which such ability is
       restricted by provisions in the Merger Agreement limiting our ability to
       solicit and respond to proposals by third parties and requiring us to pay
       a termination fee of $108 million under certain circumstances.


     - The other terms of the Merger Agreement, including the parties'
       representations, warranties, and covenants, and the conditions to their
       respective obligations. The Special Committee concluded that these terms
       provide a high degree of certainty that the Merger can be completed,
       particularly in light of Medtronic's ability to finance the transaction,
       the lack of any financing condition in the Merger Agreement, and
       Medtronic's ability to terminate the Merger Agreement only in limited
       circumstances.

     - The possible conflicts of interest inherent in the concurrent signing of
       the Medical Research Group merger agreement (in light of Mr. Mann's
       ownership interest and position as Chairman of Medical Research Group)
       and the risks associated with the possibility that a material adverse
       event with respect to, or a breach of a representation and warranty by,
       Medical Research Group, out of our control, might give Medtronic the
       right to terminate the Merger Agreement.

     - The desire of Mr. Mann, our founder, Executive Chairman and largest
       single stockholder, to engage in a transaction on terms that the Special
       Committee and our senior management believe to be in the best interests
       of our stockholders and his willingness to approve and adopt the Merger
       Agreement and to execute an Agreement to Facilitate the Merger which
       provided that he would vote his shares of Company common stock in favor
       of the approval, consent and ratification of the Merger Agreement and the
       Merger and against any proposal or action that could impede, interfere
       with, frustrate, nullify or discourage the Merger, could facilitate the
       acquisition of the Company by

                                        31
   40

       a party other than Medtronic or could reasonably result in any of the
       conditions to the obligations of the Company under the Merger Agreement
       not being fulfilled.

     The above discussion is not meant to be exhaustive, but includes the
material factors the Special Committee considered. The Board relied primarily on
the Special Committee's conclusions and recommendations relating to the
foregoing factors, the respective opinions of UBS Warburg and U.S. Bancorp Piper
Jaffray as described above, and the Board's own knowledge about our business,
strategy and risks, in making its decisions and recommendations about the Merger
and the Merger Agreement.

     Neither the Special Committee nor the Board quantified or attached any
particular weight to the various factors that they considered in reaching their
respective determinations that the Merger Agreement and the Merger are fair to
and in the best interests of our stockholders. Rather, they made their
respective determinations based on the totality of the information presented to
them, and the judgments of individual members of the Special Committee and the
Board may have been influenced to a greater or lesser degree by different
factors.

OPINION OF UBS WARBURG LLC


     On May 29, 2001, at a meeting of the Special Committee held to evaluate the
proposed Merger and later in the day at a meeting of the Board held for that
purpose, UBS Warburg delivered an oral opinion, which was confirmed by delivery
of a written opinion dated May 30, 2001, to the effect that, as of the date of
the opinion and based on and subject to various assumptions made, matters
considered and limitations described in the opinion, the merger consideration
was fair, from a financial point of view, to the holders of Company common
stock.


     The full text of UBS Warburg's opinion describes the assumptions made,
procedures followed, matters considered and limitations on the review undertaken
by UBS Warburg. This opinion is attached as Appendix B and is incorporated into
this proxy statement by reference. UBS WARBURG'S OPINION IS DIRECTED ONLY TO THE
FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE MERGER CONSIDERATION AND DOES
NOT ADDRESS ANY OTHER ASPECT OF THE MERGER. THE OPINION DOES NOT ADDRESS THE
COMPANY'S UNDERLYING BUSINESS DECISION TO EFFECT THE MERGER OR CONSTITUTE A
RECOMMENDATION TO ANY HOLDER OF COMPANY COMMON STOCK AS TO HOW SUCH STOCKHOLDER
SHOULD VOTE WITH RESPECT TO ANY MATTERS RELATING TO THE PROPOSED MERGER. HOLDERS
OF COMPANY COMMON STOCK ARE ENCOURAGED TO READ THE OPINION CAREFULLY AND IN ITS
ENTIRETY. The summary of UBS Warburg's opinion described below is qualified in
its entirety by reference to the full text of its opinion.

     In arriving at its opinion, UBS Warburg:

     - reviewed current and historical market prices and trading volumes of
       Company common stock;

     - reviewed publicly available business and historical financial information
       relating to the Company;

     - reviewed internal financial information and other data relating to the
       Company's business and financial prospects, including estimates and
       financial forecasts prepared by the Company's management, that were
       provided to or discussed with UBS Warburg by the Company and were not
       publicly available;

     - conducted discussions with members of the Company's senior management;

     - reviewed publicly available financial and stock market data with respect
       to other companies in lines of business that UBS Warburg believed to be
       generally comparable to those of the Company;

     - compared the financial terms of the Merger with the publicly available
       financial terms of other transactions that UBS Warburg believed to be
       generally relevant;

     - reviewed the Merger Agreement and other related documents; and

                                        32
   41

     - conducted other financial studies, analyses and investigations, and
       considered other information, as UBS Warburg deemed necessary or
       appropriate.

     In connection with its review, with the Company's consent, UBS Warburg did
not assume any responsibility for independent verification of any of the
information that UBS Warburg was provided or reviewed for the purpose of its
opinion and, with the Company's consent, UBS Warburg relied on that information
being complete and accurate in all material respects. In addition, at the
Company's direction, UBS Warburg did not make any independent evaluation or
appraisal of any of the assets or liabilities, contingent or otherwise, of the
Company and was not furnished with any evaluation or appraisal. With respect to
the financial forecasts and estimates relating to the Company that it reviewed,
UBS Warburg assumed, at the Company's direction, that they were reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the Company's management as to the future financial performance of
the Company. UBS Warburg's opinion was necessarily based on economic, monetary,
market and other conditions existing, and information available to UBS Warburg,
on the date of its opinion.

     UBS Warburg was not asked to, and it did not, offer any opinion as to the
terms of the Merger Agreement, other than with respect to the merger
consideration to the extent expressly stated in its opinion, or related
documents and the obligations thereunder, or the form of the Merger. In
connection with its engagement, UBS Warburg was requested to solicit indications
of interest from, and hold discussions with, selected third parties regarding
the possible acquisition of all or a part of the Company.

     In rendering its opinion, UBS Warburg assumed, with the Company's consent,
that each of the Company, Medtronic and the merger subsidiary would comply with
all material covenants and agreements set forth in, and other material terms of,
the Merger Agreement and related documents and that the Merger would be
consummated in accordance with its terms without waiver, modification or
amendment of any material term, condition or agreement. Except as described
above, the Company imposed no other instructions or limitations on UBS Warburg
with respect to the investigations made or the procedures followed by UBS
Warburg in rendering its opinion.


     In connection with rendering its opinion to the Board of Directors, UBS
Warburg performed a variety of financial and comparative analyses, which are
summarized below. The following summary is not a complete description of all of
the analyses performed and factors considered by UBS Warburg in connection with
its opinion. The preparation of a fairness opinion is a complex process
involving subjective judgments and is not necessarily susceptible to partial
analysis or summary description. With respect to the analyses of selected
publicly traded companies and selected transactions summarized below, no company
or transaction used as a comparison is either identical or directly comparable
to the Company or the Merger. These analyses necessarily involve complex
considerations and judgments concerning financial and operating characteristics
and other factors that could affect the public trading or acquisition values of
the companies concerned.


     UBS Warburg believes that its analyses and the summary below must be
considered as a whole and that selecting portions of its analyses and factors or
focusing on information presented in tabular format, without considering all
analyses and factors or the narrative description of the analyses, could create
a misleading or incomplete view of the processes underlying UBS Warburg's
analyses and opinion. None of the analyses performed by UBS Warburg was assigned
greater significance by UBS Warburg than any other. UBS Warburg arrived at its
ultimate opinion based on the results of all analyses undertaken by it and
assessed as a whole. UBS Warburg did not draw, in isolation, conclusions from or
with regard to any one factor or method of analysis.


     The estimates of the Company's future performance provided by the Company's
management in or underlying UBS Warburg's analyses are not necessarily
indicative of future results or values, which may be significantly more or less
favorable than those estimates. In performing its analyses, UBS Warburg
considered industry performance, general business and economic conditions and
other matters, many of which are beyond the Company's control. Estimates of the
financial value of companies do not necessarily purport to be appraisals or
reflect the prices at which companies actually may be sold.

     The merger consideration was determined through negotiation between the
Company and Medtronic, and the decision to enter into the Merger was solely that
of the Board of Directors, upon recommendation of the Special Committee. UBS
Warburg's opinion and financial analyses were only one of many factors
considered by the Special Committee and the Board of Directors in their
evaluation of the Merger and should not be viewed as determinative of the views
of the Special Committee, the Board of Directors or management with respect to
the Merger or the merger consideration.

     The following is a brief summary of the material financial analyses
performed by UBS Warburg and reviewed with the Special Committee and the Board
of Directors in connection with its opinion. THE FINANCIAL ANALYSES SUMMARIZED
BELOW INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. IN ORDER TO FULLY
UNDERSTAND UBS WARBURG'S FINANCIAL ANALYSES, THE TABLES MUST BE READ TOGETHER
WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A COMPLETE
DESCRIPTION OF THE FINANCIAL ANALYSES. CONSIDERING THE DATA BELOW WITHOUT
CONSIDERING THE FULL NARRATIVE DESCRIPTION OF THE FINANCIAL ANALYSES, INCLUDING
THE METHODOLOGIES AND ASSUMPTIONS UNDERLYING THE ANALYSES, COULD CREATE A
MISLEADING OR INCOMPLETE VIEW OF UBS WARBURG'S FINANCIAL ANALYSES.

     Selected Companies Comparison. UBS Warburg compared financial, operating
and stock market data of the Company to corresponding data of the following 10
publicly traded companies in the medical technology industry:

     Discounted Cash Flow Analysis. UBS Warburg performed a discounted cash flow
analysis of the Company to estimate the present value of the unlevered,
after-tax free cash flows that the Company could generate for fiscal years 2001
to 2003, based on internal estimates of the Company's management. UBS Warburg
then calculated a range of estimated terminal values by applying multiples
ranging from 22.0x to 26.0x to the Company's projected fiscal year 2003 EBITDA.
The present value of the cash flows and terminal values were then calculated
using discount rates ranging from 12.0% to 18.0%. This analysis indicated an
implied per share equity reference range for the Company of approximately $39.46
to $53.02, as compared to the per share consideration for Company common stock
in the Merger of $48.

     Terms of Engagement. The Company has agreed to pay UBS Warburg for its
financial advisory services upon completion of the Merger an aggregate fee equal
to 0.375% of the total consideration, including liabilities assumed, payable in
connection with the Merger. In addition, the Company has agreed to reimburse UBS
Warburg for its reasonable expenses, including reasonable fees and disbursements
of its counsel, and to indemnify UBS Warburg and related parties against
liabilities, including liabilities under federal securities laws, relating to,
or arising out of, its engagement.

     The Company selected UBS Warburg as its financial advisor in connection
with the Merger because UBS Warburg is an internationally recognized investment
banking firm with substantial experience in similar transactions as well as its
familiarity with the Company and its business. UBS Warburg is continually
engaged in the valuation of businesses and their securities in connection with
mergers and

                                        35
   44

acquisitions, leveraged buyouts, negotiated underwritings, competitive bids,
secondary distributions of listed and unlisted securities and private
placements.

     Other Relationships. In the ordinary course of business, UBS Warburg, its
successors and affiliates may actively trade the securities of the Company and
Medtronic for their own accounts and the accounts of their customers and,
accordingly, may at any time hold a long or short position in those securities.
UBS Warburg and its affiliates in the past have provided services to the Company
and Medtronic unrelated to the proposed Merger and have received customary
compensation for the rendering of these services. UBS Warburg and its affiliates
are also currently providing investment banking services to companies affiliated
with Mr. Mann, for which UBS Warburg expects to receive customary compensation
if a transaction is consummated.

OPINION OF U.S. BANCORP PIPER JAFFRAY INC.

     The Company retained U.S. Bancorp Piper Jaffray to act as a financial
advisor to the Special Committee and, if requested, to render to the Special
Committee an opinion as the fairness, from a financial point of view, of the $48
per share to be received by the Company's stockholders.

     On May 29, 2001, U.S. Bancorp Piper Jaffray delivered to the Special
Committee its opinion, as of that date and based upon and subject to the
assumptions, factors and limitations set forth in the written opinion and
described below, that the $48 per share to be received by the Company's
stockholders in the proposed Merger with Medtronic was fair, from a financial
point of view, to those stockholders. A copy of U.S. Bancorp Piper Jaffray's
written opinion is attached to this proxy statement as Annex C and is
incorporated into this proxy statement by reference. The Company stockholders
should read the opinion carefully in its entirety in conjunction with this proxy
statement and should carefully consider the assumptions made, matters
considered, and the limits of the review undertaken by U.S. Bancorp Piper
Jaffray.

     While U.S. Bancorp Piper Jaffray rendered its opinion and provided certain
analyses to the Special Committee, U.S. Bancorp Piper Jaffray was not requested
to and did not make any recommendation to the Special Committee as to the
specific form or amount of the consideration to be received by the Company's
stockholders in the proposed Merger with Medtronic, which was determined through
negotiations between the Company and Medtronic. U.S. Bancorp Piper Jaffray's
written opinion, which was delivered for use and considered by the Special
Committee, is directed only to the fairness, from a financial point of view, of
the $48 per share to be received by the Company's stockholders in the proposed
transaction. The opinion does not address the value of a share of the Company
common stock, does not address the Company's underlying business decision to
participate in the Merger and does not constitute a recommendation to any
Company stockholder as to how a stockholder should vote with respect to the
Merger.

     In arriving at its opinion, U.S. Bancorp Piper Jaffray reviewed, analyzed
and relied upon material relating to the financial and operating condition and
prospects of the Company and Medtronic and material prepared in connection with
the proposed Merger. These materials were:

     - a draft of the Merger Agreement dated May 29, 2001;

     - publicly available financial, operating and business information related
       to the Company;

     - publicly available market and securities data of the Company and selected
       public companies deemed comparable to the Company;

     - analyst reports relating to the Company;

     - to the extent publicly available, financial information relating to
       selected merger and acquisition transactions deemed comparable to the
       proposed Merger; and

     - internal financial information of the Company prepared for financial
       planning purposes and furnished by the Company's management.

   45

     In addition, U.S. Bancorp Piper Jaffray had discussions with management of
the Company concerning the financial condition, current operating results and
business outlook for the Company on a stand-alone basis.

     In delivering its opinion to the Special Committee on May 29, 2001, U.S.
Bancorp Piper Jaffray presented to the Special Committee various analyses and
other information material to the opinion. The following is a summary of these
analyses.

     SELECTED PUBLIC COMPANY ANALYSIS. U.S. Bancorp Piper Jaffray compared
financial information and valuation data relating to the Company from the
proposed $48 cash price per share to corresponding data and ratios from four
publicly traded companies deemed comparable to the Company (Arthrocare Corp.,
Cytyc Corp., Disetronic AG and ResMed Inc.). In its analysis, U.S. Bancorp Piper
Jaffray calculated and considered several factors, including enterprise values,
which means equity value plus debt less cash, over the latest twelve months
revenues, earnings before interest, taxes, depreciation and amortization, or
EBITDA, earnings before interest and taxes, or EBIT, ratio of price to earnings
per share, or P/E, calendar year 2001 and 2002 P/E, and calendar year 2001 ratio
of price to earnings ratio divided by earnings growth rate and price to earnings
ratio divided by revenue growth rate, or PEG ratios.

     This analysis produced multiples of selected valuation data as follows:

     PREMIUM PAID ANALYSIS. U.S. Bancorp Piper Jaffray reviewed publicly
available information for selected completed and pending transactions where a
change of control of the target occurred and that fulfill certain other
criteria. Of the transactions meeting its criteria, U.S. Bancorp Piper Jaffray
evaluated two separate groups:

     DISCOUNTED CASH FLOW ANALYSIS. U.S. Bancorp Piper Jaffray performed a
discounted cash flow analysis for the Company in which it calculated the present
value of the projected future cash flows of the Company using internal financial
planning data prepared by the Company's management. U.S. Bancorp Piper Jaffray
estimated a range of theoretical values for the Company based on the net present
value of its implied annual cash flows and a terminal value for the Company at
calendar year end 2005 calculated based upon a multiple of operating income.
U.S. Bancorp Piper Jaffray applied a range of discount rates of 15% to 25% and a
range of terminal value multiples of 18.0x to 22.0x of forecasted 2005 operating
income.

     In reaching its conclusion as to the fairness of the $48 cash price per
share, and in its presentation to the Special Committee, U.S. Bancorp Piper
Jaffray did not rely on any single analysis or factor described above, assign
relative weights to the analyses or factors considered by it, or make any
conclusion as to how the results of any given analysis, taken alone, supported
its opinion. The preparation of a fairness opinion is a complex process and not
necessarily susceptible to partial analysis or summary description. U.S. Bancorp
Piper Jaffray believes that its analyses must be considered as a whole and that
selection of portions of its analyses and of the factors considered by it,
without considering all of the factors and analyses, would create a misleading
view of the processes underlying the opinion.

     The analyses of U.S. Bancorp Piper Jaffray are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than suggested by the analyses. Analyses relating to the value of
companies do not purport to be appraisals or valuations or necessarily reflect
the price at which companies may actually be sold. No company or transaction
used in any analysis for purposes of comparison is identical to the Company or
the Merger. Accordingly, an analysis of the results of the comparisons is not
mathematical; rather, it involves complex considerations and judgments about
differences in the companies to which the Company was compared and other factors
that could affect the public trading value of the Company.

     For purposes of its opinion, U.S. Bancorp Piper Jaffray relied upon and
assumed the accuracy, completeness and fairness of the financial statements and
other information provided to it by the Company and otherwise made available to
it and did not assume responsibility for the independent verification of that
information. Information prepared for financial planning purposes was not
prepared with the expectation of public disclosure. U.S. Bancorp Piper Jaffray
relied upon the assurances of the management of the Company that the information
provided to it by the Company was prepared on a reasonable basis, the financial
planning data and other business outlook information reflect the best currently
available estimates of management, and management was not aware of any
information or facts that would make the information provided to U.S. Bancorp
Piper Jaffray incomplete or misleading.

     For purposes of its opinion, U.S. Bancorp Piper Jaffray assumed that the
final form of the Merger Agreement would be substantially similar to the last
draft it reviewed, without modification or waiver of material terms or
conditions by the Company or Medtronic. U.S. Bancorp Piper Jaffray also assumed
that, in the course of obtaining the necessary regulatory approvals for the
Merger, no restrictions, including any divestiture requirements, will be imposed
that would have a material adverse effect on the contemplated benefits of the
Merger.

     In arriving at its opinion, U.S. Bancorp Piper Jaffray did not perform any
appraisals or valuations of any specific assets or liabilities of the Company,
and was not furnished with any such appraisals or valuations. U.S. Bancorp Piper
Jaffray analyzed the Company as a going concern and accordingly expressed no
opinion as to the liquidation value of any entity. U.S. Bancorp Piper Jaffray
expressed no opinion as to the price at which shares of the Company common stock
have traded. U.S. Bancorp Piper Jaffray was not authorized to solicit, and did
not solicit, other persons regarding a business combination with the Company.
The opinion is based on information available to U.S. Bancorp Piper Jaffray and
the facts and circumstances as they existed and were subject to evaluation on
the date of the opinion. Events

                                        39
   48

occurring after that date could materially affect the assumptions used in
preparing the opinion. U.S. Bancorp Piper Jaffray has not undertaken to and is
not obligated to affirm or revise its opinion or otherwise comment on any events
occurring after the date it was given.

     U.S. Bancorp Piper Jaffray, as a customary part of its investment banking
business, evaluates businesses and their securities in connection with mergers
and acquisitions, underwritings and secondary distributions of securities,
private placements and valuations for estate, corporate and other purposes. The
Special Committee selected U.S. Bancorp Piper Jaffray because of its expertise,
reputation and familiarity with the medical technology industry in general and
with the Company in particular. U.S. Bancorp Piper Jaffray writes research on
and maintains a market in the Company common stock. In the ordinary course of
its business, U.S. Bancorp Piper Jaffray and its affiliates may actively trade
securities of the Company or Medtronic for their own accounts or the accounts of
their customers and, accordingly, may at any time hold a long or short position
in those securities.

     Under the terms of the engagement letter dated September 28, 2000, the
Company agreed to pay U.S. Bancorp Piper Jaffray $3.25 million for rendering its
opinion and financial advisory services to a previous special committee of the
Company Board, of which $1.4 million was deferred and was payable upon delivery
of the written opinion to the Special Committee relating to the Merger. Whether
or not the Merger is consummated, the Company has agreed to pay the reasonable
out-of-pocket expenses of U.S. Bancorp Piper Jaffray and to indemnify U.S.
Bancorp Piper Jaffray against liabilities incurred. These liabilities include
liabilities under the federal securities laws in connection with the engagement
of U.S. Bancorp Piper Jaffray by the Special Committee.

EFFECTS OF THE MERGER

     After the Merger becomes effective, Company stockholders will cease to have
ownership interests in the Company or rights as Company stockholders. Therefore,
the Company's current stockholders will not participate in any future earnings,
losses, growth or decline of the Company. Medtronic and its stockholders will be
the sole beneficiaries of the future earnings and growth of the Company, if any.

     As a result of the Merger, the Company will be a privately-held corporation
and there will be no public market for its common stock. After the Merger, the
common stock will cease to be listed on the Nasdaq National Market and price
quotations with respect to sales of shares of MiniMed common stock in the public
market will no longer be available. In addition, registration of the common
stock under the Securities Exchange Act of 1934, as amended, will be terminated.
This termination will make certain provisions of the Exchange Act, such as the
short-swing profit recovery provisions of Section 16(b) and the requirement of
furnishing a proxy or information statement in connection with stockholders
meetings, no longer applicable to the Company. In addition, after the effective
time of the Merger, the Company will no longer be required to file periodic
reports with the SEC.

     At the effective time of the Merger, the directors of the merger subsidiary
will become the directors of the Company, and it currently is contemplated that
substantially all of the current officers of the Company will remain in similar
capacities with the Company. It is expected that Mr. Mann will no longer serve
as an officer or director of the Company or Medtronic after the Merger. At the
effective time of the Merger, the Company's certificate of incorporation will be
amended to read as provided in the Merger Agreement. At the effective time of
the Merger, the bylaws of the merger subsidiary will become the bylaws of the
Company.

     All outstanding options to purchase Company common stock and all units
issued under the Company's Non-Employee Director Deferred Stock Units Plan will
be treated as described below under "THE MERGER AGREEMENT -- Treatment of Stock
Options" and "-- Treatment of Deferred Stock Units," respectively.

INTERESTS OF THE COMPANY'S DIRECTORS AND OFFICERS IN THE MERGER

     Alfred E. Mann is the founder, Executive Chairman and a principal
stockholder of the Company. Mr. Mann is also the founder, Chairman and a
principal stockholder of Medical Research Group, which has also entered into a
merger agreement with Medtronic under which Medical Research Group would be
acquired for approximately $420 million in cash and/or Medtronic common stock.
Mr. Mann and a corporation wholly-owned by him own approximately 32% of the
outstanding shares of Medical Research Group. In addition, the Alfred Mann
Foundation, a non-profit research organization established by Mr. Mann, owns
approximately 7.6%, the Alfred E. Mann Institute for Biomedical Engineering at
the University of Southern California, a non-profit medical research
organization funded with an endowment from Mr. Mann, owns an additional 11.2%
and the University of Southern California holds an additional 11.2% contributed
by Mr. Mann and intended to be transferred to a non-profit institute to be
established at one or more different academic institutions. The Company has the
exclusive worldwide marketing rights to the implantable pump for insulin and to
the long-term glucose sensor system. Because of these relationships, Medtronic
insisted on signing merger agreements with both companies concurrently.

     The members of the Special Committee are entitled to a special fee for
their services, in addition to their normal pre-meeting as directors. Thomas R.
Testman, the Chairman of the Special Committee, will receive $40,000, and each
of John C. Villforth and William R. Grant, the remaining members of the Special
Committee, will receive $25,000. This special fee is not contingent on the
completion of the Merger or any other transaction.


     Certain directors and executive officers hold options under the Company's
1994 option plan. These options will become fully exercisable at the effective
time of the Merger. To the extent their options are exercised at or prior to the
effectiveness of the Merger, those directors and executive officers will be
entitled to receive $48 per share in cash for each share of Company common stock
issuable upon exercise of such options on the same terms and subject to the same
conditions that apply to other holders of options under this plan. Directors and
officers will also be able to exercise their options effective at the effective
time of the Merger and receive the difference between $48 per share and the
exercise price of the options in lieu of paying the exercise price in cash.
Options not exercised at or prior to the effectiveness of the Merger will be
assumed by Medtronic and will be exercisable after the Merger to purchase shares
of Medtronic common stock. See "THE MERGER AGREEMENT -- Treatment of Stock
Options" and "PRINCIPAL STOCKHOLDERS AND STOCK OWNERSHIP OF MANAGEMENT AND
OTHERS." The rights of directors and officers described above are the same as
the rights of holders of all other outstanding stock options granted by the
Company.


     In addition, certain directors of the Company hold units issued under the
Company's Non-Employee Director Deferred Stock Units Plan, which will be
converted into the right to receive $48 per unit in cash, without interest and
minus any required withholding for tax. See "THE MERGER AGREEMENT -- Treatment
of Deferred Stock Units" and "PRINCIPAL STOCKHOLDERS AND STOCK OWNERSHIP OF
MANAGEMENT AND OTHERS."


     Medtronic is obligated to maintain the benefits of the Company's current
directors' and officers' liability insurance policy with respect to claims
arising from facts or events that occurred at or prior to the effective time of
the Merger for three years after the effective time of the Merger or provide
alternatively no less favorable insurance (subject to certain premium
limitations). Medtronic has also agreed to fulfill and guarantee existing
indemnification agreements between the Company and its officers and directors
for acts occurring at or before the effective time of the Merger and to maintain
their rights to indemnification, advancement of expenses and limitations on
liability under the Company's governing documents for at least six years after
the effective date of the Merger.


     David H. MacCallum, a director of the Company, is the Global Head of Health
Care Investment Banking at Salomon Smith Barney Inc. In connection with
providing certain services to the Company, as described in "SPECIAL
FACTORS -- Background of the Merger" and for introducing a potential acquirer to
the Company, Salomon Smith Barney will receive an aggregate fee of $2,000,000,
of which $500,000 was payable upon execution of the merger agreement executed on
May 30, 2001 and the balance
                                        41
   50

of $1,500,000 is payable upon completion of the Merger. The Company also has
agreed to reimburse Salomon Smith Barney for its reasonable expenses, including
the reasonable fees and disbursements of its counsel, and to indemnify Salomon
Smith Barney and related parties against liabilities, including liabilities
under federal securities laws, relating to, or arising out of, its services.

     In 1999, the Company entered into agreements with Messrs. Mann, Terrance H.
Gregg, Eric S. Kentor, David Morley and Kevin R. Sayer, providing for severance
benefits to these executive officers in the event of termination of their
employment in connection with a change of control of the Company occurring prior
to March 1, 2001, the two-year anniversary of such agreements. The agreements
were renewed for an additional two-year period effective March 1, 2001. In
August 1999, the Company entered into similar agreements with Messrs. Stephen A.
Bowman and Steven M. Schultz in the event of termination of their respective
employment in connection with a change of control of the Company occurring prior
to August 2001. Mr. Kevin Wells entered into a similar agreement with the
Company in October 2000 in the event of termination of his employment in
connection with a change of control of the Company occurring prior to October
2002. Messrs. Bowman's and Schultz's agreements were extended for an additional
two-year period, effective August 12, 2001. The severance benefits are payable
if the Company terminates the employment of an officer without cause or the
officer voluntarily terminates his employment for good reason (generally
consisting of adverse changes in responsibilities, compensation, benefits or
location of work place) within two years after a change of control (such as the
Merger) or three months prior to and in connection with, or in anticipation of,
such a change of control. The benefits are also payable if the officer
voluntarily terminates his employment for any reason within 30 days after the
expiration of one year after a change of control.

     In these change of control severance agreements, "change of control" is
defined to mean:

     - the acquisition of beneficial ownership of 30% or more of the outstanding
       shares of voting stock of the Company by any person, entity or group,
       subject to certain exceptions, including acquisitions by Mr. Mann and
       acquisitions of shares beneficially owned by him as a result of his death
       or transfers during his lifetime to charities or members of his family or
       certain entities in which charities or members of his family have a
       majority of the beneficial interest;

     - any change in the directors of the Company after which a majority of the
       Board of Directors of the Company consist of persons who (i) were not
       serving as directors when the severance benefit agreements were entered
       into or (ii) were selected for election by the Company's stockholders, or
       elected to fill vacancies on the Board of Directors, by directors
       referred to in clause (i) or were themselves selected or nominated as
       described in this clause (ii);

     - a sale of all or substantially all of the Company's assets, or a merger,
       consolidation or reorganization of the Company unless the holders of the
       outstanding voting shares of the Company immediately before any such
       transaction own at least 70% of the outstanding voting shares of the
       Company or a successor company immediately after the transaction; or

     - a liquidation of the Company.

     The severance benefits generally consist of a lump sum payment equal to two
times the officer's annual base salary and two times his average annual bonus
determined over the three prior years (subject to certain exceptions), a
prorated portion of the bonus for the year of termination, continuation of
Company life, health and disability insurance for two years or until any earlier
date when other full time employment is obtained providing health plan benefits
without an exclusion for pre-existing conditions, continuation of the use of a
Company car for one year or until any earlier date when other full time
employment is obtained and acceleration of the date when outstanding stock
options become exercisable. The benefits (other than acceleration of the vesting
dates of stock options) are subject to reduction to avoid the taxes and loss of
deductions associated with "excess parachute payments" under the Internal
Revenue Code.


     In addition, in connection with the Merger Agreement, four officers of the
Company, Messrs. Terrance H. Gregg, Kevin R. Sayer, David H. Morley and Stephen
A. Bowman entered into agreements

                                        42
   51

not to compete with Medtronic for the longer of five years after the effective
date of the Merger or two years after the termination of their respective
employment with the Company or Medtronic. However, these agreements will become
void unless Medtronic or the Company offers to enter into an employment
agreement with such person providing for employment for at least two years upon
terms at least as favorable as those upon which such person is currently
employed.

FINANCING FOR THE MERGER

     Medtronic estimates that approximately $3.3 billion will be required to
complete the Merger and pay the related fees and expenses. Medtronic's
obligations to complete the Merger are not subject to any conditions relating to
any financing. Medtronic expects to fund the Merger and related expenses through
cash on hand, available borrowing capacity, debt financing or other financing
alternatives that may become available to Medtronic.

LITIGATION

     As a result of the proposed Merger, the Company and its directors have been
named as defendants in a class action lawsuit filed on May 30, 2001 in the Court
of Chancery of the State of Delaware in and for New Castle County. The
plaintiffs purport to represent a class of public stockholders of the Company
whose stock will be converted into the right to receive the $48 per share cash
payment in connection with the Merger. The complaint alleges that the $48 cash
price per share to be paid to stockholders in connection with the proposed
Merger is inadequate and that the director defendants did not undertake an
appropriate process to obtain the best price reasonably available for the sale
of the Company. As a result, the plaintiffs allege that the defendant directors
breached their fiduciary duties to the Company's stockholders in approving the
Merger Agreement. In addition, the plaintiffs allege that the proposed Merger
was coupled with the sale of Medical Research Group in order to confer
substantial special benefits upon Alfred E. Mann, the founder, Executive
Chairman and the largest stockholder of the Company, and his affiliates at the
expense of a proper process to maximize value from the Merger of the Company.
The complaint seeks remedies including unspecified monetary damages, attorneys',
accountants' and expert's fees and injunctive relief that would, if granted,
prevent the completion of the Merger. The Company believes that these
allegations are without merit, and intends to vigorously defend this action.


     In addition, the Company and its directors have been named in a class
action lawsuit filed on June 6, 2001 in the Superior Court of the State of
California in and for the County of Los Angeles. The plaintiffs purport to
represent a class of stockholders of the Company asserting a claim in connection
with the alleged violation of the fiduciary duties owed by the Company and its
directors to the Company's stockholders. The complaint seeks preliminary and
permanent injunctive relief that would, if granted, prevent the completion of
the Merger. The Company and its directors have filed a motion to stay the
California action, which is set for hearing on August 13, 2001. The Company
believes that these allegations are without merit, and intends to vigorously
defend this action.


FEDERAL AND OTHER REGULATORY MATTERS


     The HSR Act and the rules and regulations promulgated thereunder require
that the Company and Medtronic file notification and report forms with respect
to the Merger and related transactions with the Antitrust Division of the United
States Department of Justice and the United States Federal Trade Commission.
After filing the required notifications and forms, the parties are required to
observe a 30-day waiting period before completing the Merger. The waiting period
may be extended by requests for additional information by the Department of
Justice or the Federal Trade Commission. In accordance with the requirements
under the HSR Act, the necessary notifications and forms were filed with the
Department of Justice and the Federal Trade Commission on June 28, 2001, and on
Friday, July 13, 2001, the waiting period was terminated prior to its normal
expiration date by the United States Federal Trade Commission. The Department of
Justice and the Federal Trade Commission, state antitrust authorities or a
private person or entity could seek to enjoin the Merger under the antitrust
laws at any time before the Merger is completed or to compel rescission or
divestiture at any time subsequent to the Merger. The

                                        43
   52

Company also intends to comply with the requirements of all applicable foreign
merger laws. We cannot predict whether we will obtain all required regulatory
approvals for the Merger, or whether any approvals will include conditions that
may be detrimental to Medtronic or the Company.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES TO STOCKHOLDERS

     The following is a summary of the material U.S. federal income tax
consequences of the Merger to holders of Company common stock (including holders
exercising appraisal rights). This summary is based on laws, regulations,
rulings and decisions now in effect, all of which are subject to change,
possibly with retroactive effect. This summary does not address all of the U.S.
federal income tax consequences that may be applicable to a particular holder of
Company common stock or to holders who are subject to special treatment under
U.S. federal income tax law (including, for example, banks, insurance companies,
tax-exempt investors, S corporations, dealers in securities, non-U.S. persons,
holders who hold their common stock as part of a hedge, straddle or conversion
transaction, and holders who acquired their common stock through the exercise of
employee stock options or other compensation arrangements). In addition, this
summary does not address the tax consequences of the Merger under applicable
state, local or foreign laws.

     YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE PARTICULAR TAX
CONSEQUENCES TO YOU OF THE MERGER, INCLUDING THE EFFECT OF ANY FEDERAL, STATE,
LOCAL OR FOREIGN TAX LAWS.

     The receipt of cash by holders of Company common stock pursuant to the
Merger or upon exercise of appraisal rights will be a taxable transaction for
U.S. federal income tax purposes. A holder of Company common stock generally
will recognize gain or loss in an amount equal to the difference between the
merger consideration received by such holder and such holder's adjusted tax
basis in the common stock. That gain or loss generally will be capital gain or
loss if the common stock is held as a capital asset at the effective time of the
Merger. Any capital gain or loss generally will be long-term capital gain or
loss if the common stock has been held by the holder for more than one year. If
the common stock has been held by the holder for less than one year, any gain or
loss generally will be taxed as a short-term capital gain or loss.

ACCOUNTING TREATMENT

     The Merger will be accounted for under the purchase method of accounting.

APPRAISAL RIGHTS

     Under Section 262 of the General Corporation Law of the State of Delaware
any holder of common stock who does not wish to accept $48 per share in cash for
their shares of common stock may elect to have the "fair value" of the holder's
shares of common stock (exclusive of any element of value arising from the
expectation or accomplishment of the Merger) judicially determined and paid to
the holder in cash, together with a fair rate of interest, if any, provided that
the holder complies with the requirements of Section 262.

     The following discussion is not a complete statement of the law pertaining
to appraisal rights under the General Corporation Law of the State of Delaware
and is qualified in its entirety by the full text of Section 262, which is
attached as Appendix D to this proxy statement. All references in Section 262
and in this summary to a "stockholder" are to the record holder of the shares of
common stock as to which appraisal rights are asserted. A PERSON HAVING A
BENEFICIAL INTEREST IN SHARES OF COMMON STOCK HELD OF RECORD IN THE NAME OF
ANOTHER PERSON, SUCH AS A BROKER OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE
RECORD HOLDER TO FOLLOW PROPERLY THE STEPS SUMMARIZED BELOW AND IN A TIMELY
MANNER TO PERFECT APPRAISAL RIGHTS.

     Under Section 262, where a proposed merger is to be submitted for approval
and adoption at a meeting of stockholders, as in the case of the special
meeting, the corporation, not less than 20 days before the meeting, must notify
each of its stockholders entitled to appraisal rights that appraisal rights are

                                        44
   53

available and include in that notice a copy of Section 262. This proxy statement
constitutes that notice to the holders of the Company common stock, and the
applicable statutory provisions of the General Corporation Law of the State of
Delaware are attached to this proxy statement as Appendix D. Any Company
stockholder who wishes to exercise appraisal rights or who wishes to preserve
the right to do so should review carefully the following discussion and Appendix
D to this proxy statement. FAILURE TO COMPLY WITH THE PROCEDURES SPECIFIED IN
SECTION 262 TIMELY AND PROPERLY WILL RESULT IN THE LOSS OF YOUR APPRAISAL
RIGHTS. Moreover, because of the complexity of the procedures for exercising the
right to seek appraisal of the common stock, we believe that stockholders who
consider exercising such appraisal rights should seek the advice of counsel.

     Any holder of common stock wishing to exercise their appraisal rights under
Section 262 of the General Corporation Law of the State of Delaware must satisfy
each of the following conditions:

     - as more fully described below, the holder must deliver to the Company a
       written demand for appraisal of the holder's shares BEFORE the vote on
       the Merger Agreement at the special meeting, which demand will be
       sufficient if it reasonably informs the Company of the identity of the
       holder and that the holder intends to demand the appraisal of the
       holder's shares;

     - the holder must NOT vote the holder's shares of common stock in favor of
       the Merger Agreement and the holder must NOT consent to the Merger in
       writing. A proxy which does not contain voting instructions will, unless
       revoked, be voted in favor of adoption of the Merger Agreement, and
       therefore, a stockholder who votes by proxy and who wishes to exercise
       appraisal rights must vote AGAINST the adoption of the Merger Agreement
       or ABSTAIN from voting on adoption of the Merger Agreement; AND

     - the holder must continuously hold the shares from the date of making the
       demand through the effective time of the Merger. A stockholder who is the
       record holder of shares of common stock on the date the written demand
       for appraisal is made but who thereafter transfers those shares before
       the effective time of the Merger will lose any right to appraisal of
       those shares.

     Neither voting against (whether in person or by proxy), abstaining from
voting on or failing to vote on the proposal to adopt the Merger Agreement will
constitute a written demand for appraisal within the meaning of Section 262. THE
WRITTEN DEMAND FOR APPRAISAL MUST BE IN ADDITION TO AND SEPARATE FROM ANY SUCH
PROXY OR VOTE.

     Only a holder of record of shares of common stock issued and outstanding
immediately before the effective time of the Merger is entitled to assert
appraisal rights for the shares of common stock registered in that holder's
name. A demand for appraisal should be executed by or on behalf of the
stockholder of record, fully and correctly, as the stockholder's name appears on
the stock certificates, should specify the stockholder's name and mailing
address, the number of shares of common stock owned and that the stockholder
intends to demand appraisal of the stockholder's common stock. If the shares are
owned of record in a fiduciary capacity, such as by a trustee, guardian or
custodian, execution of the demand should be made in that capacity. If the
shares are owned of record by more than one person, as in a joint tenancy or
tenancy in common, the demand should be executed by or on behalf of all owners.
An authorized agent, including one or more joint owners, may execute a demand
for appraisal on behalf of a stockholder, but the agent must identify the record
owner or owners and expressly disclose the fact that, in executing the demand,
the agent is acting as agent for such owner or owners. A record holder such as a
broker who holds shares as nominee for several beneficial owners may exercise
appraisal rights with respect to the shares held for one or more beneficial
owners while not exercising appraisal rights with respect to the shares held for
one or more beneficial owners; in such case, the written demand should set forth
the number of shares as to which appraisal is sought, and where no number of
shares is expressly mentioned the demand will be presumed to cover all shares
held in the name of the record owner. STOCKHOLDERS WHO HOLD THEIR SHARES IN
BROKERAGE ACCOUNTS OR OTHER NOMINEE FORMS AND WHO WISH TO EXERCISE APPRAISAL
RIGHTS ARE URGED TO CONSULT WITH THEIR BROKERS TO DETERMINE APPROPRIATE
PROCEDURES FOR THE MAKING OF A DEMAND FOR APPRAISAL BY THE NOMINEE.

should mail or deliver a written demand to: MiniMed Inc., 18000 Devonshire
Street, Northridge, California 91325, Attention: Eric S. Kentor, Secretary.

     Within ten days after the effective time of the Merger, the Company must
send a written notice of the effectiveness of the Merger to each former
stockholder of the Company who has made a written demand for appraisal in
accordance with Section 262 and who has not voted to adopt the Merger Agreement
and the transactions contemplated by the Merger Agreement or consented thereto
in writing. Within 120 days after the effective time of the Merger, but not
thereafter, either the Company or any stockholder who has complied with the
requirements of Section 262 may file a petition in the Delaware Court of
Chancery demanding a determination of the value of the shares of common stock
held by all dissenting stockholders. The Company is under no obligation to file
a petition for appraisal and has no present intent to do so, and therefore
stockholders seeking to exercise appraisal rights should not assume that the
Company will file such a petition or that the Company will initiate any
negotiations with respect to the fair value of the shares. Accordingly,
stockholders who desire to have their shares appraised should initiate any
petitions necessary for the perfection of their appraisal rights within the time
periods and in the manner prescribed in Section 262. SINCE THE COMPANY HAS NO
OBLIGATION OR INTENTION TO FILE SUCH A PETITION, THE FAILURE OF A STOCKHOLDER TO
DO SO WITHIN THE PERIOD SPECIFIED COULD NULLIFY THE STOCKHOLDER'S PREVIOUS
WRITTEN DEMAND FOR APPRAISAL.

     Within 120 days after the effective time of the Merger, any stockholder who
has complied with the provisions of Section 262 to that point in time will be
entitled to receive from the Company, upon written request, a statement setting
forth the aggregate number of shares not voted in favor of the Merger Agreement
and with respect to which demands for appraisal have been received and the
aggregate number of holders of such shares. The Company must mail that statement
to the stockholder requesting such information in writing within 10 days of
receipt of the request or within 10 days after expiration of the period for
delivery of demands for appraisals under Section 262, whichever is later.

     A stockholder timely filing a petition for appraisal with the Delaware
Court of Chancery must serve a copy upon the Company, which will then be
obligated within 20 days to provide the Delaware Court of Chancery with a duly
verified list containing the names and addresses of all stockholders who have
demanded appraisal of their shares. After notice to those stockholders, the
Delaware Court of Chancery is empowered to conduct a hearing on the petition to
determine which stockholders are entitled to appraisal rights. The Delaware
Court of Chancery may require stockholders who have demanded an appraisal of the
"fair value" of their shares and who hold stock represented by certificates to
submit their certificates to the Register in Chancery for notation on the stock
certificates of the pendency of the appraisal proceedings, and if any
stockholder fails to comply with the requirement, the Delaware Court of Chancery
may dismiss the appraisal proceedings as to that stockholder.

     After determining the stockholders entitled to an appraisal, the Delaware
Court of Chancery will appraise the "fair value" of those stockholders' shares,
exclusive of any element of value arising from the expectation or accomplishment
of the Merger, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. The costs of the action may be
determined by the Delaware Court of Chancery and taxed upon the parties as the
Delaware Court of Chancery deems equitable. Upon application of a stockholder
seeking an appraisal of common stock, the Delaware Court of Chancery may also
order that all or a portion of the expenses incurred by any stockholder in
connection with the appraisal proceeding, including, without limitation,
reasonable attorneys' fees and the fees and expenses of experts, be charged pro
rata against the value of all of the shares entitled to appraisal. STOCKHOLDERS
CONSIDERING SEEKING APPRAISAL SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR
SHARES AS DETERMINED UNDER SECTION 262 COULD BE MORE THAN, THE SAME AS OR LESS
THAN THE $48 PER SHARE THEY WOULD RECEIVE UNDER THE MERGER AGREEMENT IF THEY DID
NOT SEEK APPRAISAL OF THEIR SHARES. STOCKHOLDERS SHOULD ALSO BE AWARE THAT
INVESTMENT BANKING OPINIONS AS TO FAIRNESS ARE NOT NECESSARILY OPINIONS AS TO
FAIR VALUE UNDER SECTION 262.

                                        46
   55

     In determining fair value and, if applicable, a fair rate of interest, the
Delaware Court of Chancery is to take into account all relevant factors. In
Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods that are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." In
Weinberger, the Delaware Supreme Court stated that "elements of future value,
including the nature of the enterprise, which are known or susceptible of proof
as of the date of the merger and not the product of speculation, may be
considered." Section 262 provides that fair value is to be "exclusive of any
element of value arising from the accomplishment or expectation of the merger."

     Any stockholder who has duly and timely demanded an appraisal in compliance
with Section 262 will not, after the effective time of the Merger, be entitled
to vote the shares subject to that demand for any purpose or be entitled to the
payment of dividends or other distributions on those shares (except dividends or
other distributions payable to holders of record of shares as of a record date
before the effective time of the Merger).

     Any stockholder may withdraw its demand for appraisal and accept the $48
per share payable pursuant to the Merger (without interest and minus any
required withholding for tax) by delivering a written withdrawal of the
stockholder's demand for appraisal to the Company, except that (a) any attempt
to withdraw made more than 60 days after the effective time of the Merger will
require written approval of the Company and (b) no appraisal proceeding in the
Delaware Court of Chancery will be dismissed as to any stockholder without the
approval of the Delaware Court of Chancery, and such approval may be conditioned
upon such terms as the Delaware Court of Chancery deems just. If the Company
does not approve a stockholder's request to withdraw a demand for appraisal when
that approval is required, or if the Delaware Court of Chancery does not approve
the dismissal of an appraisal proceeding, the stockholder would be entitled to
receive only the appraised value determined in any such appraisal proceeding,
which value could be more than, the same as or less than $48 per share.

     FAILURE TO COMPLY STRICTLY WITH ALL OF THE PROCEDURES SET FORTH IN SECTION
262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE MAY RESULT IN THE
LOSS OF A STOCKHOLDER'S STATUTORY APPRAISAL RIGHTS. CONSEQUENTLY, ANY
STOCKHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS IS URGED TO CONSULT LEGAL
COUNSEL BEFORE ATTEMPTING TO EXERCISE APPRAISAL RIGHTS.

                              THE MERGER AGREEMENT

     The description of the Merger Agreement contained in this proxy statement
describes the material terms of the Merger Agreement. The actual legal terms of
the Merger Agreement are in Appendix A to this proxy statement, which contains
the complete text of the Merger Agreement and is incorporated into this proxy
statement by this reference. You should read the entire Merger Agreement, as it
is the legal document that governs the Merger.

THE MERGER

     The Merger Agreement provides that, subject to the satisfaction or waiver
of the conditions summarized below, the merger subsidiary will merge with and
into the Company at the effective time of the Merger. As a result of the Merger,
the merger subsidiary will cease to exist as a separate entity, and the Company
will survive the Merger as a wholly-owned subsidiary of Medtronic.

EFFECTIVE TIME OF THE MERGER

     The Merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware in accordance with the
General Corporation Law of the State of Delaware, unless the Company, Medtronic
and the merger subsidiary agree upon a later time and specify such time in the
certificate of merger. We refer to this time as the "effective time." The Merger
Agreement provides that the certificate of merger will be filed not later than
the second business day after satisfaction or waiver of the conditions to the
Merger contained in the Merger Agreement, unless the Company and Medtronic agree
upon another time.

MERGER CONSIDERATION

     In the Merger, each share of common stock of the Company issued and
outstanding immediately before the effective time of the Merger automatically
will be canceled and converted into the right to receive $48 per share in cash,
without interest, with the following exceptions:

     - shares owned by the Company, Medtronic, the merger subsidiary, or any
       other wholly-owned subsidiary of the Company or Medtronic automatically
       will be canceled in the Merger without any payment; and

     - shares held by Company stockholders who properly perfect their appraisal
       rights under Delaware law will be subject to appraisal to determine the
       "fair value" of those shares in accordance with Delaware law, exclusive
       of any element of value arising from the expectation or accomplishment of
       the Merger.

     At the effective time of the Merger, each share of common stock of the
merger subsidiary issued and outstanding immediately prior to the effective time
of the Merger will be converted into one share of common stock of the Company,
as the corporation surviving the Merger.

TREATMENT OF STOCK OPTIONS

     All outstanding options to purchase shares of Company common stock issued
pursuant to the Company's Third Amended and Restated 1994 Stock Incentive Plan
and under the MiniMed Technologies Limited Amended and Restated 1992 Option Plan
(which were assumed by the Company) will automatically become exercisable in
full at the effective time of the Merger, will be assumed by Medtronic and will
become exercisable to purchase shares of Medtronic common stock after the
effective time of the Merger. The Merger Agreement provides that the Company is
required to give notice to option holders at least 30 days prior to the
effective time of the Merger stating that (i) the options will become fully
exercisable at the effective time of the Merger, (ii) the holder of any option
which is exercised prior to the effective time of the Merger will receive shares
of Company common stock which will be converted into the right to receive $48
per share at the effective time of the Merger, (iii) the holder of any option
exercised prior to but effective upon the effectiveness of the Merger will
receive $48 per share, or the
                                        48
   57

difference between $48 per share and the exercise price for option holders who
elect to receive that amount in lieu of paying the option exercise price in
cash, and (iv) options outstanding after the effective time of the Merger will
be assumed by Medtronic and will be exercisable after the Merger to purchase
shares of Medtronic common stock.

     Options which remain outstanding after the Merger will be exercisable to
purchase the number of shares of Medtronic common stock having a value at the
time of the Merger that corresponds to the $48 per share for the Company common
stock. The value of Medtronic common stock at the time of the Merger, for
purposes of this calculation, will be deemed to equal the average of the closing
prices of Medtronic common stock on the New York Stock Exchange for the ten
trading days ending three trading days prior to the date the Merger becomes
effective. Thus, for each share of Company common stock for which an option was
exercisable at or prior to the effectiveness of the Merger, the option will
become exercisable to purchase that number of shares of Medtronic common stock
determined by dividing $48 by the value of the Medtronic common stock
(determined as described above). The aggregate exercise price of each option
will remain the same, and the exercise price per share of Medtronic common stock
then subject to the option will equal the aggregate price divided by the number
of shares of Medtronic stock issuable upon exercise of the option.

TREATMENT OF ESPP OPTIONS

     The Company's Employee Stock Purchase Plan and all purchase rights under
the plan will be canceled at the effective time of the Merger. The Merger
Agreement provides that the Company will give notice to holders of options under
the Employee Stock Purchase Plan at least 30 days prior to the effective time of
the Merger, stating that all outstanding options to purchase shares of Company
common stock under the plan have been accelerated for a 30-day period from the
date of the notice. On the 30th day after the date of the notice, all rights to
purchase shares of Company common stock outstanding under the Employee Stock
Purchase Plan immediately prior to such date automatically will be exercised
(unless the participant withdraws from the plan) and each share of Company
common stock issued upon exercise will be converted into the right to receive
$48 per share in cash at the effective time of the Merger, without interest and
minus any required withholding for tax. After May 30, 2001 no offering or
purchase periods under the plan will be commenced and participants in the
Employee Stock Purchase Plan will not be allowed to increase their level of
participation after that date. In accordance with the requirements of the Merger
Agreement, the Employee Stock Purchase Plan and all rights under that plan will
be terminated as of the effective time of the Merger.

TREATMENT OF DEFERRED STOCK UNITS


     At the effective time of the Merger, all outstanding units issued pursuant
to the Company's Non-Employee Director Deferred Stock Units Plan will terminate
and will represent only the right to receive $48 per share in cash, without
interest. The Merger Agreement provides that the Company is required to give
notice to holders of outstanding deferred stock units at least 30 days prior to
the effective time of the Merger to that effect and stating that the units will
not be assumed in the Merger.


TRANSFER OF SHARES

     No transfers of shares of Company common stock will be made on the stock
transfer books of the Company after the effective time of the Merger.

DIRECTORS, OFFICERS AND GOVERNING DOCUMENTS

     From and after the effective time of the Merger, the directors of the
merger subsidiary, none of whom are officers or directors of the Company, will
become the directors of the Company until successors are duly elected and
qualified. It is currently anticipated that substantially all of the officers of
the Company at the time of the Merger will continue in similar capacities after
the Merger. However, it is expected that Mr. Mann no longer will serve as either
an officer or director of the Company or Medtronic after the

                                        49
   58

Merger. At the effective time of the Merger, the Company's certificate of
incorporation will be amended to read as provided in the Merger Agreement. At
the effective time of the Merger, the bylaws of the merger subsidiary will
become the bylaws of the Company, as the corporation surviving the Merger.

warranty. You are urged to read the sections in the Merger Agreement titled
"Representations and Warranties of the Company" and "Representations and
Warranties of Parent and Merger Sub" in Appendix A of this proxy statement. The
representations and warranties in the Merger Agreement do not survive the
effective time of the Merger.

CONDUCT OF BUSINESS OF THE COMPANY PRIOR TO THE MERGER

     The Company has agreed that, prior to the effective time of the Merger, the
Company and its subsidiaries will carry on their respective businesses in the
ordinary course of business consistent with past practice and will use their
commercially reasonably efforts to preserve intact their business organizations
and relationships with third parties and keep available the services of their
current officers and employees. The Merger Agreement further provides that,
except as expressly provided in the Merger Agreement, during the period from the
date of the Merger Agreement to the effective time of the Merger, the

                                        51
   60


Company will not, and will not permit any of its subsidiaries to, take any of
the following actions, among others, without the prior written consent of
Medtronic:


     - amend its governing documents;

     - authorize for issuance, issue, sell, pledge or deliver any stock of any
       class or any securities exercisable for the purchase of, or convertible
       into, shares of stock of any class, except for shares of Company common
       stock issued under previously granted options or deferred stock units;

     - split, combine or reclassify any shares of capital stock, declare, set
       aside or pay any dividend or other distribution, or redeem or otherwise
       acquire any shares of its capital stock or other securities, or amend or
       alter any material term of any of its outstanding securities;

     - incur, assume or guarantee any indebtedness (subject to certain
       exceptions), make any loans, allow any lien on any material asset, make
       any tax elections or permit the termination of any insurance;

     - increase or accelerate the compensation or benefits of any director,
       officer, employee or consultant;

     - sell, transfer, mortgage, lease, license, pledge or dispose of or
       encumber any material assets or properties;

     - acquire or agree to acquire any business or material assets;


     - make or agree to make any capital expenditure or expenditures in excess
       of $200,000 per month individually or $2,000,000 per month in aggregate
       capital expenditures made pursuant to the Company's budget, subject to
       certain exceptions;


     - enter into, terminate, amend, extend, renew or modify certain material
       contracts, subject to certain exceptions;

     - materially change the Company's general credit policy relating to sales
       of inventories or collection of receivables or inventory consignment
       practices used by the Company;

     - remove property from its facilities, except in the ordinary course of
       business consistent with past practice;

     - change any of its accounting principles, procedures, methods or
       practices;

     - institute, settle or compromise any pending or threatened claim, action,
       suit or proceeding before an governmental entity or any nongovernmental
       self-regulatory agency;

     - knowingly take any action, or fail to take any action, that would render
       any representation, warranty, covenant or agreement of the Company in the
       Merger Agreement inaccurate, in a way that would cause the conditions to
       the Merger not to be satisfied; and

     - agree or consent to take any of the foregoing actions.

LIMITATIONS ON SOLICITATION OF COMPETING TRANSACTIONS

     The Merger Agreement provides that the Company will not, and will cause its
officers, directors, advisors, representatives or other agents or agents of its
subsidiaries not to, directly or indirectly, solicit, initiate or knowingly
encourage discussions of any "acquisition proposal," which includes any proposal
to acquire the Company or any of its subsidiaries. That restriction also extends
to discussions and negotiations relating to any such acquisition proposal and
the providing of nonpublic information or otherwise facilitating any effort or
attempt to make an acquisition proposal. There is an exception, however, if an
unsolicited proposal is received that the Special Committee reasonably and in
good faith determines is a superior proposal, as defined below. In such event,
the Special Committee may furnish non-public information to or enter into
discussions or negotiations with the third party if:

     - the failure of the Company's Board of Directors to take action with
       respect to the proposal would be a breach of its fiduciary duty to the
       Company's stockholders;

                                        52
   61

     - the Company gives Medtronic five business days written notice prior to
       acting on the superior proposal and the third party enters into a
       confidentiality agreement with terms no less favorable to the Company
       than the confidentiality agreement between Medtronic and the Company;

     - non-public information not previously provided to Medtronic is given to
       the third party and Medtronic at the same time; and

     - the Company keeps Medtronic informed of the status, terms and conditions
       of any discussions or negotiations.

     The Merger Agreement defines "acquisition proposal" to mean any of the
following:

     - a tender offer, exchange offer, merger, consolidation, share exchange,
       business combination or similar transaction involving more than 50% of
       capital stock of the Company or any of its subsidiaries;

     - the acquisition of 50% of more of the outstanding shares of any class of
       capital stock of the Company or any of its subsidiaries by a party other
       than Medtronic or the merger subsidiary; or

     - the acquisition of more than 20% of the assets of the Company and its
       subsidiaries by a party other than Medtronic or the merger subsidiary
       involving any sale, lease, exchange, licensing, transfer or other
       disposition in a single transaction or series of related transactions.

     The Merger Agreement defines a "superior proposal" as a bona fide
acquisition proposal that the Special Committee of the Board of Directors
reasonably and in good faith determines, (with the advice of its financial
advisors and taking into account all material legal, financial and regulatory
aspects of the acquisition proposal) is more favorable to the Company's
stockholders than the transactions contemplated in the Merger Agreement. Also,
for an acquisition to be a "superior proposal," the financing required to
consummate the contemplated transaction must be committed, or the Special
Committee of the Board of Directors must have determined in good faith, after
consultation with its financial advisor, that the financing is likely to be
obtained on a timely basis.

     The Merger Agreement requires the Company to terminate all discussions
regarding any acquisition proposal from any party other than Medtronic and to
request that all such parties promptly return any confidential information
previously provided by the Company. Subject to the Company's rights described
above, the Company also agreed not to waive any provision of any
confidentiality, standstill or similar agreement entered into with any party
other than Medtronic and to enforce all such agreements in accordance with their
terms. The Company must also communicate to Medtronic the name of any person
submitting an acquisition proposal, and provide a detailed description of the
terms and conditions of any acquisition proposal. In addition, the Company is
obligated to provide to Medtronic a reasonably detailed description of any
information requested from the Company, or of any negotiations initiated or
continued with the Company after May 30, 2001 regarding any acquisition proposal
from a party other than Medtronic.

     The Merger Agreement includes a provision which may have the effect of
deterring other parties from making acquisition proposals for the Company.
Medtronic has agreed that it will not consummate the acquisition of Medical
Research Group prior to the effectiveness of the Merger involving the Company,
but there is an exception permitting Medtronic to acquire Medical Research Group
without acquiring the Company. This exception applies under circumstances where
the termination fee described under "Termination Fee" below is payable and
includes situations where a competing acquisition proposal is made. There is a
corresponding provision in the Medical Research Group merger agreement
permitting the acquisition of Medical Research Group to be consummated under
those circumstances.

     The ability of Medtronic to acquire Medical Research Group under such
circumstances may make the Company less attractive to other potential acquiring
parties because of the relationship between the Company and Medical Research
Group. Among other things, the Company has the worldwide exclusive distribution
rights to an implantable pump owned by Medical Research Group and a long-term
glucose monitoring system being developed by Medical Research Group. The Company
also has substantial
                                        53
   62

minimum purchase requirements with respect to Medical Research Group implantable
pumps and other significant financial commitments involving Medical Research
Group. See "Special Factors -- Relationship with Medical Research Group." A
party acquiring the Company under circumstances where Medtronic acquires Medical
Research Group would be in the position of having to deal with Medtronic on the
various aspects of the relationship and would not get any benefits of combining
the two businesses under common ownership.

EMPLOYEE BENEFITS

     Medtronic has agreed to provide employee benefits and programs to the
Company's employees that are substantially comparable to or more favorable than
those in effect on May 30, 2001. In addition, Medtronic will give Company
employees who remain employees following the Merger full credit for service
accrued under employee benefit plans or arrangements maintained by the Company
for purposes of eligibility, level of participation and vesting, except that no
credit for service accrued will be given for benefit accruals under any employee
pension benefit plan.

DIRECTOR AND OFFICER LIABILITY

     The Company and Medtronic have agreed that all rights to indemnification
and advancement of expenses and all limitations on liability provided in the
Company's governing documents will continue for at least six years after the
effective time of the Merger.

     The Merger Agreement provides that Medtronic and the Company, as the
corporation surviving the Merger, will indemnify and hold harmless and advance
expenses to the fullest extent permitted by applicable law to those individuals
who on or prior to the effective time of the Merger were directors, officers,
employees or agents of the Company.

     Medtronic and the Company, as the corporation surviving the Merger, have
agreed to fulfill and honor in all respects the obligations under the
indemnification agreements between the Company and its officers and directors.
Furthermore, Medtronic agrees to guarantee the obligations of the Company, as
the corporation surviving the Merger, with respect to the indemnification and
payment of fees and expenses provisions contained in the Company's governing
documents for acts occurring at or before the effective time of the Merger.

     Medtronic is also obligated to maintain the benefits of the Company's
current directors' and officers' liability insurance policy with respect to
claims arising from facts or events that occurred at or prior to the effective
time of the Merger for three years after the effective time of the Merger or
provide alternatively no less favorable insurance (subject to certain premium
limitations).

ACCESS TO INFORMATION

     The Company has agreed to give Medtronic and its representatives access at
reasonable times during normal business hours to its personnel, properties,
offices and other facilities and its books and records and those of its
subsidiaries. The Company will also furnish Medtronic such information as
Medtronic may reasonably request and permit Medtronic to conduct a reasonable
audit of the Company's compliance with requirements of the Food and Drug
Administration, relations and dealings with third party physicians and other
clinical investigators and consultants, and related performance and compliance
matters concerning the products of the Company and its subsidiaries.

CONFIDENTIALITY

     The Company and Medtronic have entered into a confidentiality agreement
relating to all documents and information provided to the other party in
connection with the Merger.

MEDICAL RESEARCH GROUP TRANSACTION

     The Merger Agreement provides that Medtronic will not consummate the merger
with Medical Research Group prior to the effective time of the Merger with the
Company unless the Merger Agreement with the Company has been terminated in a
manner that results or could result in the termination fee described under
"Termination Fee" below being paid to Medtronic. See "Limitations on
Solicitation of Competing Transactions." Medtronic has agreed not to amend or
modify the Medical Research Group merger agreement or waive any rights under
that agreement in a manner that would reasonably be expected to prevent or delay
the effective time of the Merger with the Company or the timely closing of the
transactions contemplated under the Medical Research Group merger agreement.

CONDITIONS TO COMPLETING THE MERGER

     The obligations of the Company, Medtronic and the merger subsidiary to

       Company must adopt the Merger Agreement;

     - the applicable waiting period under the HSR Act and any applicable
       foreign merger laws must have expired or terminated; and

     - there must be no provision of applicable law and no final order, decree

       Merger or would impose any material limitation on the ability of
       Medtronic effectively to exercise full rights of ownership of the Company
       or the assets or business of the Company or its subsidiaries.


     The Company's obligations to complete the Merger are subject to the

       Agreement must be true and correct in all material respects on the

       under the Merger Agreement at or before the effective time of the Merger;

     - the representations and warranties made by the Company in the Merger
       Agreement must be true and correct in all respects on the closing date,
       except where the failure of such representations and warranties to be
       true and correct has not had, or could not reasonably be expected to
       have, a "material adverse effect" on the Company, as defined below;

     - Medtronic must receive certificates signed by the chief executive officer
       of the Company stating that as of the closing date of the Merger the two
       preceding conditions have been satisfied or waived;

     - the Company must obtain all necessary third party permits,
       authorizations, consents and approvals, except for permits,
       authorizations, consents and approvals that if not obtained could not

                                        55
   64

     - all applicable waiting periods under the HSR Act or any foreign merger
       law relating to the transactions contemplated by the Medical Research
       Group merger agreement must have expired or been terminated;

     - Medtronic must receive executed agreements in a form satisfactory to

       Company's subsidiaries to persons designated by Medtronic;

       "material adverse effect" on the Company;

     - the representations and warranties made by Medical Research Group in its
       merger agreement with Medtronic must be true and correct, except for any

       adverse effect on the Company and Medical Research Group, taken as a
       whole; and

     - there must have been no change, event, occurrence, state of facts or
       development with respect to Medical Research Group that individually or
       in the aggregate, has had or could reasonably be expected to have a
       material adverse effect on the Company and Medical Research Group, taken
       together as a whole.


On Friday, July 13, 2001, the waiting period under the HSR Act was terminated
prior to its normal expiration date with respect to both the Merger and the
transactions contemplated by the Medical Research Group merger agreement.


     "Material adverse effect" on the Company means any change, effect, event,
occurrence, state of facts or development that is or could reasonably be
expected to be materially adverse to: (a) the business (including its prospects,
current products or products identified for development), assets, financial
condition or results of operations of the Company and its subsidiaries taken
together as a whole; or (b) the Company's ability to perform any of its material
obligations under the Merger Agreement or to consummate the Merger; or (c) the
ability of Medtronic or the Company as the corporation surviving the Merger, to
conduct the businesses of the Company and its subsidiaries taken as a whole as
previously conducted, or proposed to be conducted; or (d) the ability of
Medtronic or the Company as the corporation surviving the Merger to exercise
full rights of ownership of the Company or its assets or businesses, except in
each case for any change, effect, event, occurrence, state of facts or
developments resulting from (i) changes in general economic, regulatory or
political conditions or (ii) changes in the medical device industry generally.

     The Merger Agreement requires that Medtronic will give the Company prompt
notice upon learning of any fact or circumstance that Medtronic determines would
lead to the closing conditions in either of the two immediately preceding bullet
points above not being met. In such event, Medtronic must keep the Company
informed of the status, facts, and other material information with respect to
any such matter (on a daily basis or more frequently if the context requires or
the Company requests). Medtronic has agreed that, at the Company's request, the
Company and its representatives may be directly involved in any discussion or
negotiations with respect to any problems meeting either of the two immediately
preceding closing conditions, and the Company and its representatives also will
be afforded a reasonable opportunity to actively participate in resolving such
problems in a manner reasonably satisfactory to Medtronic.

     In addition, the Merger Agreement requires the Company and Medtronic to
promptly notify the other party in writing after becoming aware of the
occurrence of any event that would, or would be reasonably likely to, result in
the failure to satisfy any of the conditions to the notifying party's
obligations specified in the Merger Agreement.

TERMINATION OF THE MERGER AGREEMENT

     The Company and Medtronic may mutually agree to terminate the Merger
Agreement at any time before the effective time of the Merger, whether or not
the Company stockholders have voted to adopt the Merger Agreement. In addition,
either party may terminate the Merger Agreement if, among other things:

     - the Merger has not been completed by December 31, 2001, or such other
       date as the Company and Medtronic agree, subject to certain required
       extensions to as late as March 31, 2002 if additional information is
       requested in connection with the filings under the HSR Act or pursuant to
       any applicable foreign merger laws;

     - a court of competent jurisdiction or an administrative, governmental or
       regulatory authority in the United States or the European Union has taken
       any action having the effect of permanently restraining, enjoining or
       otherwise prohibiting the Merger;

     - the Company's stockholders do not adopt the Merger Agreement at the
       special meeting, except that no party can terminate the Merger Agreement
       for this reason if that party's actions caused, or resulted in, the
       failure of the Company's stockholders to adopt the Merger Agreement; or

     - the other party has materially breached any of its representations,
       warranties or obligations under the Merger Agreement and the party
       desiring to terminate the Merger Agreement is not in material breach of
       its representations, warranties or obligations; provided that the
       non-breaching party cannot terminate the Merger Agreement for this reason
       if the material breach can be cured by the breaching party with
       commercially reasonable efforts and the cure is reasonably likely to be
       completed before December 31, 2001 or such other date as the Company and
       Medtronic agree upon, in each case subject to the required extensions to
       as late as March 31, 2002 if additional information is requested in
       connection with the filings under the HSR Act or pursuant to any
       applicable foreign merger laws.

     In addition, Medtronic may terminate the Merger Agreement if, among other
things:

     - the Company breaches in any material respect its obligations under the
       Merger Agreement not to solicit, initiate or encourage other proposals to
       acquire the Company or participate in or encourage discussions or
       negotiations or provide non-public information concerning other
       acquisition proposals or facilitate or implement any such proposals;

     - the Board of Directors of the Company withdraws or modifies or amends its
       approval or recommendation of the Merger in any respect adverse to
       Medtronic or the merger subsidiary;

     - the Board of Directors of the Company recommends another proposal to
       acquire control of the Company or more than 20% of the Company's assets
       to the Company's stockholders or resolves or announces an intention to do
       so; or

     - a tender offer or exchange offer for 50% or more of the outstanding
       shares of the Company common stock is announced or commenced and either
       the Board of Directors of the Company recommends acceptance of the offer
       by the Company's stockholders or the Board of Directors fails to
       recommend against acceptance of such offer within 10 business days after
       the offer commences.

     The Company may also terminate the Merger Agreement prior to the adoption
of the Merger Agreement by the Company's stockholders if the Company has
complied with all requirements, conditions and procedures regarding its
non-solicitation obligations under the Merger Agreement referred to above in all
material respects and if all of the following occur:

     - the Board of Directors of the Company has, upon the Special Committee's
       recommendation and in accordance with the provisions of the Merger
       Agreement, authorized the Company to enter into a binding written
       agreement that is a "superior proposal," as defined in the Merger
       Agreement and described in "Limitations of Solicitation of Competing
       Transactions" above, and notifies Medtronic that it intends to enter into
       such an agreement;

                                        57
   66

     - Medtronic does not make, within five business days after receipt of the
       notice from the Company, a proposal that the Special Committee determines
       (reasonably and in good faith and after consultation with its legal and
       financial advisors) is at least as favorable to the Company's
       stockholders as the Superior Proposal;

     - during that five business day period the Company reasonably considers and
       discusses in good faith all proposals submitted by Medtronic and meets
       with and causes its financial and legal advisors to meet with Medtronic
       and its advisors to consider Medtronic's proposals; and

     - the Company pays Medtronic the termination fee of $108 million described
       in the following section.

TERMINATION FEE

     The Company must pay Medtronic a termination fee of $108 million if
Medtronic terminates the Merger Agreement because (a) the Board of Directors
withdraws or modifies in any respect adverse to Medtronic or the merger
subsidiary its recommendation of the Merger, (b) the Board of Directors
recommends to the stockholders any other acquisition proposal or has resolved or
announced its intentions to do so, or (c) a tender offer or exchange offer for
50% or more of the outstanding shares of the Company Common Stock is announced
or commenced and either the Board of Directors recommends acceptance of the
offer or fails to recommend against it within 10 business days of when it
commences.

     In addition, the Company must pay the termination fee if two sets of
conditions arise:

     - the Company or Medtronic has terminated the Merger Agreement because the
       Merger was not consummated within the time period specified in the Merger
       Agreement or the Company has materially breached its obligations with
       respect to other acquisition proposals described above, or the
       stockholders of the Company have failed to vote to adopt the Merger
       Agreement; and

     - another acquisition proposal was made public and remained pending at the
       time of the termination of the Merger Agreement or the special meeting of
       stockholders and, within 12 months after termination of the Merger
       Agreement, the Company enters into a definitive agreement with respect to
       another acquisition proposal or the transaction contemplated by another
       acquisition proposal is consummated.

     The Company also has to pay the termination fee if the Merger Agreement is
terminated by us as permitted by the Merger Agreement so that we may enter into
a binding written agreement regarding a superior proposal.

     In addition, if we do not pay the termination fee to Medtronic when it
becomes due, we must pay any costs and expenses incurred by Medtronic in
collecting the termination fee, including any legal fees and expenses, and must
also pay interest on the amount of the termination fee that is not paid when it
becomes due. Medtronic must pay our costs and expenses, including legal fees and
expenses, if Medtronic files a lawsuit or takes other legal action against us to
collect the termination fee and does not prevail.

AMENDMENT, MODIFICATION AND WAIVER

     The Merger Agreement may be amended, modified or waived by the parties at
any time prior to the closing date of the Merger. However, no amendments can be
made by the parties after the Company's stockholders adopt the Merger Agreement,
except in accordance with applicable law.

                                RIGHTS AGREEMENT

     The Company has entered into a Rights Agreement dated as of July 24, 1995
between the Company and Harris Trust Company of California, as subsequently
amended. Computershare Investor Services LLC has succeeded to the rights and
obligations of Harris Trust as rights agent. Pursuant to the Rights Agreement,
one right was distributed as a dividend on each share of Company common stock
outstanding at the close of business on July 24, 1995, and one right has been
and will continue to be issued with each

                                        58
   67

share of Company common stock issued after that date. The rights trade in tandem
with the shares of Company common stock and are not represented by separate
certificates. The Rights Agreement was entered into to ensure that any
acquisition of the Company will be one in which all Company stockholders can
receive fair and equal treatment and to guard against partial tender offers,
open market accumulations and other abusive tactics that might result in unfair
or unequal treatment of the Company's stockholders.

     The rights generally become exercisable to purchase common stock only after
certain specified events or transactions in which a person becomes the
beneficial owner of 15% or more of the outstanding Company common stock. When
the rights become exercisable to purchase common stock, they can be exercised to
purchase shares at a 50% discount to the market price at the time of exercise.
However, the rights of any person that becomes a 15% stockholder become null and
void. The effect is to severely dilute the stock holdings of any person who
acquires 15% or more of the Company common stock.

     In addition if, after a person becomes a 15% stockholder, the Company is
acquired in a merger or consolidation in which: (a) the Company is not the
surviving corporation, or (b) the Company common stock is exchanged for stock or
assets of another person, or (c) 50% or more of the Company's consolidated
assets or earning power are transferred, the rights are exercisable for shares
of common stock of the surviving or acquiring corporation at a 50% discount to
the market price of that corporation's common stock. The effect of these
transactions is to allow the Company's stockholders to acquire significant
amounts of stock of an acquiring company at a substantial discount to the market
price of those securities, thereby diluting the stock ownership of the other
stockholders of the acquiring company.

     The rights agreement specifies that certain parties who hold 15% of more of
the outstanding shares of Company common stock are excluded for purposes of
determining whether their stock ownership would cause the rights to become
exercisable. The Rights Agreement also contains other customary exclusions for
events that do not cause the rights to become exercisable, such as an increase
in a person's percentage stock ownership resulting solely from a decrease in the
total number of outstanding shares of Company common stock.

     The Board of Directors can redeem the rights or amend the terms of the
Rights Agreement, subject to certain limitations. The Company's Board of
Directors has amended the Rights Agreement to specify that:

     - Medtronic will not be deemed to beneficially own securities of the
       Company that are subject to the voting agreements entered into in
       connection with the Merger Agreement before, concurrently with or after
       the execution and delivery of the Merger Agreement;

     - Medtronic will not be deemed to beneficially own any securities owned by
       any of the parties to the voting agreements other than Medtronic;

     - the execution and delivery of the voting agreements, the Merger
       Agreement, and the consummation of the transactions contemplated thereby
       will not be deemed to result in any person or entity becoming a 15%
       stockholder;

     - the execution and delivery of the voting agreements or the Merger
       Agreement or the consummation of the transaction contemplated thereby
       will not result in any event which would trigger the distribution or
       exercisability of the rights; and

     - all rights will expire upon the effectiveness of the Merger without any
       payment by the Company or Medtronic and with neither of them having
       obligations under the Rights Agreement and no person having any rights
       under the Rights Agreement except for the payment of any fees, expenses
       and indemnification to which the rights agent is entitled.

                               FEES AND EXPENSES

     Whether or not the proposed Merger is consummated, and except as otherwise
described in this proxy agreement, all fees and expenses incurred in connection
with the Merger will be paid by the party incurring those fees and expenses,
except the Company will pay for all costs and expenses of printing and mailing
this proxy statement and soliciting the related proxies.

     AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER, dated as of June 19,
2001 (this "Agreement"), by and among MiniMed Inc., a Delaware corporation (the
"Company"), Medtronic, Inc., a Minnesota corporation ("Parent") and MMI Merger
Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Parent
("Merger Sub").


                                   WITNESSETH

     WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company, and Parent as sole stockholder of Merger Sub, have each approved this
Agreement and the merger of Merger Sub with and into the Company, upon the terms
and subject to the conditions set forth herein, and in accordance with the
General Corporation Law of the State of Delaware (the "DGCL"), whereby each
issued and outstanding share of common stock, par value $0.01 per share (the
"Common Stock"), of the Company (other than shares of Common Stock owned,
directly or indirectly, by the Company or by Merger Sub immediately prior to the
Effective Time (as defined in Section 1.1(b) hereof)), will, upon the terms and
subject to the conditions and limitations set forth herein, be converted into
the right to receive the Merger Consideration (as defined in Section 1.2(b)
hereof) in accordance with the provisions of Article I of this Agreement.

     WHEREAS, the parties have previously entered into an Agreement and Plan of
Merger dated as of May 30, 2001 and now desire to amend and restate that
agreement in its entirety to read as set forth herein; provided that all
references herein to "the date hereof," "the date of this Agreement" or similar
variations thereof shall refer to May 30, 2001.

     NOW, THEREFORE, in consideration of the representations, warranties,
covenants, agreements and conditions set forth herein, and intending to be
legally bound hereby, the parties hereto agree as follows:

                                   ARTICLE I

                                   THE MERGER

     SECTION 1.1  The Merger.

     (a) Upon the terms and subject to the conditions of this Agreement, and in
accordance with the DGCL, at the Effective Time (as defined in Section 1.1(b),
Merger Sub shall be merged (the "Merger") with and into the Company, whereupon
the separate existence of Merger Sub shall cease, and the Company shall continue
as the surviving corporation (sometimes referred to herein as the "Surviving
Corporation") and shall continue to be governed by the DGCL.

     (b) Concurrently with the Closing (as defined in Section 1.7 hereof), the
Company, Parent and Merger Sub shall cause a certificate of merger (the
"Certificate Of Merger") with respect to the Merger to be executed and filed
with the Secretary of State of the State of Delaware (the "Secretary Of State")
as provided in the DGCL and shall make all other filings or recordings required
by the DGCL in connection with the Merger. The Merger shall become effective on
the date and time at which the Certificate of Merger has been duly filed with
the Secretary of State or at such later date and time as is agreed between the
parties and specified in the Certificate of Merger, and such date and time is
hereinafter referred to as the "Effective Time."

     (c) The Merger shall have the effects set forth in the DGCL. Without
limiting the generality of the foregoing and subject thereto, from and after the
Effective Time, the Surviving Corporation shall possess all properties, rights,
privileges, immunities, powers and franchises and be subject to all of the
obligations, restrictions, disabilities, liabilities, debts and duties of the
Company and Merger Sub.

     SECTION 1.2  Effect On Common Stock. At the Effective Time:

          (a) Cancellation of Shares of Common Stock. Each share of Common Stock
     held by the Company as treasury stock and each share of Common Stock owned
     by Parent, Merger Sub or any direct or indirect wholly-owned subsidiary of
     Parent or the Company immediately prior to the Effective Time shall
     automatically be cancelled and cease to exist, and no consideration or
     payment shall be delivered

                                       A-1
   76

     therefor or in respect thereto. All shares of Common Stock to be converted
     into the right to receive the Merger Consideration pursuant to this Section
     1.2 shall, by virtue of the Merger and without any action on the part of
     the holders thereof, cease to be outstanding, be cancelled and cease to
     exist, and each holder of a Certificate (as defined in Section 1.3(b))
     shall thereafter cease to have any rights with respect to such shares of
     Common Stock, except the right to receive the Merger Consideration into
     which such shares of Common Stock have been converted.

          (b) Conversion of Shares of Common Stock. Subject to Section 1.3(d)
     hereof, each share of Common Stock issued and outstanding immediately prior
     to the Effective Time (other than shares of Common Stock referred to in the
     first sentence of Section 1.2(a) hereof and Dissenting Shares (as defined
     in Section 1.2(c)) shall, by virtue of the Merger and without any action on
     the part of the holder thereof, be converted into the right to receive an
     amount of cash, without interest, equal to $48.00 (the "Merger
     Consideration").

          (c) Dissenting Shares.

             (i) Any shares of Common Stock held by a holder who has demanded
        and perfected appraisal rights for such shares in accordance with
        Section 262 of the DGCL and who, as of the Effective Time, has not
        effectively withdrawn or lost such appraisal rights ("Dissenting
        Shares") shall not be converted into or represent a right to receive
        Merger Consideration pursuant to Section 1.2(b), but the holder thereof
        shall only be entitled to such rights as are granted by the DGCL.

             (ii) Notwithstanding the provisions of subsection (i) above, if any
        holder of shares of Common Stock who demands appraisal of such shares
        under the DGCL shall effectively withdraw or lose (through failure to
        perfect or otherwise) such holder's appraisal rights, then, as of the
        later of (A) the Effective Time or (B) the occurrence of such event,
        such holder's shares of Common Stock shall automatically be converted
        into and represent only the right to receive Merger Consideration as
        provided in Section 1.2(b), without interest thereon, upon surrender of
        the Certificate representing such shares.

             (iii) The Company shall give Parent (A) prompt notice of its
        receipt of any written demands for appraisal of any shares of Common
        Stock, withdrawals of such demands, and any other instruments relating
        to the Merger served pursuant to the DGCL and received by the Company
        and (B) the opportunity to direct all negotiations and proceedings with
        respect to demands for appraisal of any shares of Common Stock under the
        DGCL. The Company shall not, except with the prior written consent of
        Parent or as may be required under applicable law (in which case Parent
        shall be consulted), voluntarily make any payment with respect to any
        demands for the appraisal of Common Stock or offer to settle or settle
        any such demands or approve any withdrawal of such demands.

          (d) Closing of the Company's Transfer Books. At the Effective Time,
     the stock transfer books of the Company shall be closed and no transfer of
     Common Stock shall thereafter be made. If, after the Effective Time,
     Certificates are presented to the Surviving Corporation, they shall be
     cancelled and exchanged for the Merger Consideration as provided in this
     Article I, subject to applicable law in the case of Dissenting Shares.

          (e) Conversion of Common Stock of Merger Sub. Each share of common
     stock of Merger Sub issued and outstanding immediately prior to the
     Effective Time shall be converted into one share of common stock of the
     Surviving Corporation with the same rights, powers and privileges as the
     shares so converted and shall constitute the only outstanding shares of
     capital stock of the Surviving Corporation.

     SECTION 1.3  Exchange Of Certificates.

     (a) Prior to the mailing of the Proxy Statement (as defined in Section 3.9
hereof) a bank, trust company or other person reasonably acceptable to the
Company shall be designated by Parent to act as the depositary and paying agent
for the delivery of the Merger Consideration in exchange for shares of Common
Stock (the "Paying Agent") in connection with the Merger. From time to time, as
necessary, at or following the Effective Time, Parent shall deposit, or cause to
be deposited, with the Paying Agent the amount needed to pay the

                                       A-2
   77

portion of the aggregate Merger Consideration for the benefit of the holders of
shares of Common Stock which are converted into the right to receive the Merger
Consideration pursuant to Section 1.2(b) hereof for which Certificates have been
surrendered or payment is otherwise due (the "Exchange Fund"). For purposes of
this Agreement, "person" means any natural person, firm, individual,
corporation, limited liability company, partnership, association, joint venture,
company, business trust, trust or any other entity or organization, whether
incorporated or unincorporated, including a government or political subdivision
or any agency or instrumentality thereof.

     (b) As of or promptly following the Effective Time, the Surviving
Corporation shall cause the Paying Agent to mail to each holder of record of a
certificate or certificates, which immediately prior to the Effective Time
represented outstanding shares of Common Stock (other than Dissenting Shares)
(the "Certificates"), (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Paying Agent and
which shall be in the form and have such other provisions as Parent and the
Company may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration into
which the number of shares of Common Stock previously represented by such
Certificate shall have been converted into the right to receive pursuant to this
Agreement. Upon surrender of a Certificate for cancellation to the Paying Agent,
together with a letter of transmittal duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may
reasonably be required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each share of Common Stock formerly represented by such
Certificate, to be distributed as soon as practicable after the Effective Time,
and the Certificate so surrendered shall be forthwith cancelled. The Paying
Agent shall accept such Certificates upon compliance with such reasonable terms
and conditions as the Paying Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices.

     (c) Any portion of the Exchange Fund which remains undistributed to the
holders of Certificates for six months after the Effective Time shall be
delivered to Parent, upon demand, and any holders of shares of Common Stock
prior to the Merger who have not theretofore complied with this Article I shall
thereafter look for payment of their claim, as general creditors thereof, only
to Parent for their claim for Merger Consideration, without interest.

     (d) None of Parent, the Company or the Paying Agent shall be liable to any
person in respect of any Merger Consideration held in the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to one year after the Effective Time (or immediately prior to such earlier
date on which Merger Consideration in respect of such Certificate would
otherwise escheat to or become the property of any Governmental Entity (as
defined in Section 3.3(b) hereof)), any such Merger Consideration in respect of
such Certificate shall, to the extent permitted by applicable law, become the
property of Parent, free and clear of all claims or interest of any person
previously entitled thereto.

     SECTION 1.4  Transfer Taxes; Withholding. If any Merger Consideration is to
be remitted to a person other than the person in whose name the Certificate
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the Certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other Taxes (as defined
in Section 3.11(b) hereof) required by reason of the remittance of such Merger
Consideration to a person other than the registered holder of the Certificate so
surrendered, or shall establish to the satisfaction of the Paying Agent that
such Tax either has been paid or is not applicable. Parent or the Paying Agent
shall be entitled to deduct and withhold from the Merger Consideration otherwise
payable pursuant to this Agreement to any holder of shares of Common Stock such
amounts as Parent or the Paying Agent are required to deduct and withhold under
the Internal Revenue Code of 1986, as amended (the "Code"), or any provision of
state, local or foreign Tax law, with respect to the making of such payment. To
the extent that amounts are so withheld by Parent or the Paying Agent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of shares of Common Stock in respect of whom such
deduction and withholding was made by Parent or the Paying Agent.

     SECTION 1.5  Stock Options; Stock Units; Stock Purchase Plan.

     (a) As to options to purchase Common Stock outstanding under the Company's
Third Amended and Restated 1994 Stock Incentive Plan (the "1994 Company
Options"):

          (i) Not later than 30 days prior to the Effective Time, the Company
     shall send a notice (the "Option Notice") to all holders of 1994 Company
     Options stating: (A) that such options, by their terms, become exercisable
     in full as to the aggregate number of shares subject thereto at the
     Effective Time, (B) that the holder of any 1994 Company Options exercised
     prior to the Effective Time shall receive shares of Common Stock which will
     be converted into the right to receive $48 per share at the Effective Time,
     (C) that the holder of any 1994 Company Options exercised prior to but
     effective as of the Effective Time will receive $48 per share or, if
     exercised on a net basis pursuant to Section 1.5(a)(iii), the amount
     specified therein, and (D) that options outstanding after the Effective
     Time will be assumed by Parent and be exercisable to purchase shares of
     Parent common stock as provided in Section 1.5(a)(iv).

          (ii) The Company shall permit each holder of a 1994 Company Option who
     desires to exercise all or any portion of such 1994 Company Option
     following receipt of the Option Notice to exercise such 1994 Company Option
     prior to the Effective Time. To the extent 1994 Company Options would not
     be exercisable but for the Merger, such exercises may be made contingent on
     the Merger becoming effective.


          (iii) The Company shall offer to all holders of 1994 Company Options a
     procedure not provided in the agreements evidencing such options whereby
     the option holders may elect to exercise their options in advance of, but
     effective at, the Effective Time and not pay the exercise price in cash
     upon exercise but instead receive after the Effective Time the excess, if
     any, of (A) the product of the Merger Consideration multiplied by the
     aggregate number of shares of Common Stock subject to such 1994 Company
     Option immediately prior to the Effective Time over (B) the aggregate
     exercise price of all such shares of Common Stock subject to such 1994
     Company Option. The aggregate amount payable pursuant to this Section
     1.5(a)(iii) and Section 1.5(b)(ii) shall hereinafter be referred to as the
     "Option Cash-Out Amount." In no event shall the procedure described in this
     Section 1.5(a)(iii) be available with respect to 1994 Company Options
     assumed by Parent pursuant to Section 1.5(a)(iv).


          (iv) Each 1994 Company Option outstanding immediately after the
     Effective Time shall, without any action on the part of the holder thereof,
     be assumed by Parent in such manner that Parent (i) is a corporation
     "assuming a stock option in a transaction to which Section 424(a) applies"
     within the meaning of Section 424 of the Code and the regulations
     thereunder or (ii) to the extent that Section 424 of the Code does not
     apply to any such 1994 Company Option, would be such a corporation were
     Section 424 of the Code applicable to such 1994 Company Option. After the
     Effective Time, all references to the Company in the 1994 Company Options
     shall be deemed to refer to Parent. The 1994 Company Options assumed by
     Parent shall be exercisable upon the same terms and conditions except that
     (i) such 1994 Company Options shall entitle the holder to purchase from
     Parent the number of shares of Parent common stock (rounded down to the
     nearest whole number of such shares) that equals (X) the number of shares
     of Common Stock subject to such 1994 Company Option immediately prior to
     the Effective Time, multiplied by (Y) the quotient of $48 divided by the
     Formula Value of the Parent common stock, (ii) the option exercise price
     per share of Parent common stock shall be an amount (rounded up to the
     nearest full cent) equal to (X) the option exercise price per share of
     Common Stock in effect immediately prior to the Effective Time divided by
     (Y) the quotient of $48 divided by the Formula Value of the Parent common
     stock. The Formula Value of the Parent common stock will equal the average
     (rounded to the nearest full cent, with the cents rounded up if the third
     decimal place is 5 or more) of the closing sale prices (rounded to the
     nearest whole cent) of Parent common stock, on the New York Stock Exchange
     ("NYSE") Composite Tape as reported in The Wall Street Journal, for the ten
     (10) consecutive NYSE trading days ending on and including the NYSE trading
     day that is three NYSE trading days prior to the Effective Time.

     (b) As to options to purchase Common Stock issued under the MiniMed
Technologies Limited Amended and Restated 1992 Option Plan (the "1992 Plan") and
assumed by the Company (the "1992 Company Options"):

          (i) The committee of the Board of Directors administering the 1992
     Plan has accelerated the exercise dates of all outstanding 1992 Company
     Options contingent upon and effective as of the Effective Time so that all
     such options will be exercisable in full at that time.


          (ii) The Company shall offer to all holders of 1992 Company Options a
     procedure not provided in the agreements evidencing such options whereby
     the option holders may elect to exercise their options in advance of, but
     effective at, the Effective Time and not pay the exercise price in cash
     upon exercise but instead receive after the Effective Time the excess, if
     any, of (A) the product of the Merger Consideration multiplied by the
     aggregate number of shares of Common Stock subject to such 1992 Company
     Option immediately prior to the Effective Time over (B) the aggregate
     exercise price of all such shares of Common Stock subject to such 1992
     Company Option. The aggregate amount payable pursuant to this Section
     1.5(b)(ii) shall be included in the Option Cash-Out Amount as provided in
     Section 1.5(a)(iii) above. In no event shall the procedure described in
     this Section 1.5(b)(ii) be available with respect to 1992 Company Options
     assumed by Parent pursuant to Section 1.5(b)(iii).



          (iii) Each 1992 Company Option outstanding immediately after the
     Effective Time shall, without any action on the part of the holder thereof,
     be assumed by Parent in such manner that Parent (i) is a corporation
     "assuming a stock option in a transaction to which Section 424(a) applies"
     within the meaning of Section 424 of the Code and the regulations
     thereunder or (ii) to the extent that Section 424 of the Code does not
     apply to any such 1992 Company Option, would be such a corporation were
     Section 424 of the Code applicable to such 1992 Company Option. After the
     Effective Time, all references to the Company in the 1992 Company Options
     shall be deemed to refer to Parent. The 1992 Company Options assumed by
     Parent shall be exercisable upon the same terms and conditions except that
     (i) such 1992 Company Options shall entitle the holder to purchase from
     Parent the number of shares of Parent common stock (rounded down to the
     nearest whole number of such shares) that equals (X) the number of shares
     of Common Stock subject to such 1992 Company Option immediately prior to
     the Effective Time, multiplied by (Y) the quotient of $48 divided by the
     Formula Value of the Parent common stock and (ii) the option exercise price
     per share of Parent common stock shall be an amount (rounded up to the
     nearest full cent) equal to (X) the option exercise price per share of
     Common Stock in effect immediately prior to the Effective Time divided by
     (Y) the quotient of $48 divided by the Formula Value of the Parent common
     stock.


          (iv) The 1994 Company Options and the 1992 Company Options are
     referred to collectively in this Agreement as the "Company Options."

     (c) Non-Employee Director Deferred Stock Units Plan. Not later than 30 days
prior to the Effective Time, the Company shall send a notice to the holders of
outstanding units issued pursuant to the Non-Employee Director Deferred Stock
Units Plan (the "Units") stating: (i) that the Units shall not be assumed in
connection with the Merger, (ii) that rights under any Units outstanding as of
the Effective Time shall terminate and be cancelled at the Effective Time and
represent only the right to receive the consideration, if any, specified in this
Section 1.5(c) in accordance with this Agreement, and (iii) setting forth the
Merger Consideration. At the Effective Time, each Unit shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into, and represent only, the right to receive, upon delivery thereof to the
Company, an amount in cash equal to the Merger Consideration. The aggregate
amount payable pursuant to this paragraph (c) shall hereinafter be referred to
as the "Unit Cash-Out Amount."

     (d) Exchange Procedures for Company Options or Units. Promptly following
the Effective Time, Parent shall cause the Paying Agent to mail to each holder
of a Company Option exercised as of the Effective Time and to each holder of a
Unit outstanding at the Effective Time (i) a letter of transmittal (which shall
be in such form and have such other provisions as Parent may reasonably
specify), and (ii) instructions for use in receiving cash payable in respect of
such Company Options or Units. Upon the delivery of such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
together with the

                                       A-5
   80

documentation representing such Company Options or Units surrendered thereby, to
the Paying Agent, the holders of such Company Options shall be entitled to
receive the Option Cash-Out Amount or other amount payable to them in respect of
such Company Options pursuant to Section 1.5(a) or (b) or the Unit Cash-Out
Amount payable to them pursuant to Section 1.5(c).

     (e) ESPP. Not later than 30 days prior to the Effective Time, the Company
shall send notice to the holders of options under the Company's Employee Stock
Purchase Plan (the "ESPP") accelerating the exercise of such options for a 30
day period from the date of the notice. On the 30th day after the date of the
notice, in accordance with the terms of the ESPP, all rights to purchase shares
of Common Stock outstanding under the ESPP immediately prior to that date shall
be exercised (unless the participant withdraws as provided in the ESPP) and each
share of Common Stock purchased pursuant to such exercise shall, by virtue of
the Merger, and without any action on the part of the holder thereof, be
converted into the right to receive the Merger Consideration payable in respect
thereof. Any Common Stock issued pursuant to the ESPP shall be deemed issued and
outstanding at the Effective Time. The Company will offer to the participants in
the ESPP a procedure not provided for in the ESPP whereby no certificates
representing Common Stock of the Company will be issued upon exercise of the
options and after the Effective Time the holders will be entitled to receive
from the Paying Agent the Merger Consideration for each share of Common Stock
issued upon exercise of such options. Parent will make appropriate arrangements
with the Paying Agent so that participants in the ESPP who elect not to receive
stock certificates upon exercise of their options will be able to receive the
Merger Consideration to which they are entitled without the submission of stock
certificates. No offering or purchase periods under the ESPP shall be commenced
after the date hereof, no participant in the ESPP shall be permitted to increase
his or her level of participation in the ESPP after the date hereof, and the
ESPP and all purchase rights thereunder shall be terminated effective as of the
Effective Time.

     (f) Registration of Parent Common Stock. Parent will prepare and file with
the United States Securities and Exchange Commission (the "SEC") a registration
statement on Form S-8 (or any successor form) under the Securities Act of 1933,
as amended, and the rules and regulations thereunder (the "Securities Act"),
with respect to the shares of Parent common stock subject to the Company Options
assumed by Parent pursuant to Section 1.5(a) and (b), and, where applicable,
will use commercially reasonable efforts to have such registration statement
become effective at or prior to the Effective Time and to maintain the
effectiveness of such registration statement covering such Company Options (and
maintain the current status of the prospectus contained therein or required
pursuant thereto) for so long as any of such Company Options remain outstanding.

     SECTION 1.6  Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Paying Agent will pay the Merger Consideration to which the holder thereof is
entitled pursuant to this Article I in exchange for such lost, stolen or
destroyed Certificate.

     SECTION 1.7  Merger Closing. Subject to the satisfaction or waiver of the
conditions set forth in Article VI hereof, the closing of the Merger (the
"Closing") will take place at 10:00 a.m., California time, on the date that the
Company's stockholders vote to adopt this Agreement in accordance with the DGCL,
or as soon thereafter as, and in any event no later than the second business day
after, the conditions set forth in Article VI hereof have been satisfied or
waived, or on such other date and/or at such other time as Parent and the
Company may mutually agree. The date on which the Closing actually occurs is
referred to herein as the "Closing Date." The Closing shall take place by
telecopy exchange of signature pages with originals to follow by overnight
delivery, or in such other manner or at such place as the parties hereto may
agree. At the Closing, subject to the provisions of Article VI, Parent, Merger
Sub, and the Company shall cause the Certificate of Merger to be filed in
accordance with Section 1.1(b), and shall take any and all other lawful actions
and do any and all other lawful things necessary to cause the Merger to become
effective to the extent provided in Section 5.7.

     SECTION 2.3  Directors. The directors of Merger Sub immediately prior to

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except (i) as set forth in a document (the "Company Disclosure Schedule")
of even date herewith and concurrently delivered herewith, referring
specifically to the representations and warranties in this Agreement and which
identifies by section number the section of this Article III to which such
disclosure relates unless the relevance and magnitude of such disclosure to
another section of this Agreement is reasonably evident, without the need for
additional information or explanation, from the contents of the referenced
disclosure or the nature of the document in question, or (ii) as specifically
described through express disclosure of current, specific facts (excluding
statements of possibilities, potential risks or general qualifications) set
forth in the Company's Annual Report on Form 10-K for the fiscal year ended
December 29, 2000, in the Company's Quarterly Report on Form 10-Q for the
quarter ended March 30, 2001, or in the Company's 2001 Proxy Statement, to the
extent the relevancy of such disclosure to such particular representation and
warranty is readily apparent, the Company hereby makes the following
representations and warranties to Parent and Merger Sub:

     SECTION 3.1  Corporate Existence And Power. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except for failures to have any such
License which could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect (as defined below). The Company is
duly qualified to do business as a foreign corporation and is in good standing
in each jurisdiction where the character of the property owned, leased or
operated by it or the nature of its activities makes such qualification
necessary, except in such jurisdictions where failures to be so qualified could
not reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. As used herein, the term "Company Material Adverse
Effect" means any change, effect, event, occurrence, state of facts or
development that is or could reasonably be expected to be materially adverse to
(i) the business (including its prospects, current products or products
identified for development), assets, financial condition or results of
operations of the Company and its Subsidiaries, taking the Company and its
Subsidiaries together as a whole; or (ii) the Company's ability to perform any
of its material obligations under this Agreement or to consummate the Merger; or
(iii) the ability of the Surviving Corporation or Parent to conduct such
business, as presently conducted or proposed to be conducted, following the
Effective Time or the ability of Parent to exercise full rights of ownership of
the Company or its assets or business, except in each case for any such change,
effect, event, occurrence, state of facts or development resulting from (i)
changes in general economic, regulatory or political conditions, or (ii) changes
in the medical device industry generally. The Company has heretofore delivered
or made available to Parent or its advisers complete and accurate copies of the
Certificate or Articles of Incorporation, Bylaws and other governing instruments
of the Company and each Subsidiary, as currently in effect, and of the
organizational documents and agreements defining the rights of the Company or
any Subsidiary with respect to any material joint ventures, partnerships or
other business in which the Company owns a less-than-100% interest. Neither the
Company nor any Subsidiary, directly or

                                       A-7
   82

indirectly, owns or controls or has any equity, partnership, or other ownership
interest in any corporation, partnership, joint venture, or other business
association or entity that is material to the Company and its Subsidiaries,
considered as a whole. For purposes of this Agreement, "Subsidiary" means with
respect to any person, any corporation or other legal entity of which such
person owns, directly or indirectly, more than 50% of the outstanding stock or
other equity interests, the holders of which are entitled to vote for the
election of the board of directors or other governing body of such corporation
or other legal entity.

     SECTION 3.2  Corporate Authorization.

     (a) The Company has the requisite corporate power and authority to execute
and deliver this Agreement and, subject to adoption of this Agreement by the
Company's stockholders as set forth in Section 3.2(b) hereof and as contemplated
by Section 5.3 hereof, to perform its obligations hereunder. The execution and
delivery of this Agreement and the performance of its obligations hereunder have
been duly and validly authorized, and this Agreement has been unanimously
approved, by the Board of Directors and the Special Committee of the Company
originally established on May 11, 2000 by the Board of Directors and
reconstituted and reaffirmed on February 9, 2001 (as constituted from time to
time, the "Special Committee") of the Company, and no other action of the
Company's Board of Directors or the Special Committee or corporate proceedings
on the part of the Company or any Subsidiary of the Company, other than the
adoption of this Agreement by the Company's stockholders, are necessary to
authorize the execution, delivery and performance of this Agreement or to
consummate the transactions contemplated hereby. The Board of Directors of the
Company and the Special Committee have declared the advisability of this
Agreement. This Agreement has been duly executed and delivered by the Company
and constitutes, assuming due authorization, execution and delivery of this
Agreement by Parent and Merger Sub, a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms, subject
to laws of general application relating to bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws affecting
creditors rights generally, and general equitable principles (whether considered
in a proceeding in equity or at law).

     (b) Under applicable law, the current Certificate of Incorporation of the
Company and the rules of The Nasdaq Stock Market, the affirmative vote of the
holders of a majority of the shares of Common Stock outstanding on the record
date, established by the Board of Directors of the Company in accordance with
the Bylaws of the Company, applicable law and this Agreement, is the vote
required for the stockholders of the Company to adopt this Agreement.

     SECTION 3.3  Consents And Approvals; No Violations.

     (a) Neither the execution and delivery of this Agreement nor the
performance by the Company of its obligations hereunder will (i) conflict with
or result in any breach of any provision of the current Certificate of
Incorporation or the Bylaws of the Company; (ii) result in a violation or breach
of, result in the creation of any Lien on any properties or assets owned or used
by the Company or any Subsidiary pursuant to, or constitute (with or without due
notice or lapse of time or both) a default (or give rise to any right of
termination, cancellation or acceleration or obligation to repurchase, repay,
redeem or acquire or any similar right or obligation) under, any of the terms,
conditions or provisions of any note, mortgage, letter of credit, other evidence
of indebtedness, guarantee, license, lease or agreement or similar instrument or
obligation to which the Company or any of its Subsidiaries is a party or by
which any of them or any of their assets may be bound; or (iii) assuming that
the filings, registrations, notifications, authorizations, consents and
approvals referred to in subsection (b) below have been obtained or made, as the
case may be, violate any order, injunction, decree, statute, rule or regulation
of any Governmental Entity to which the Company or any of its Subsidiaries is
subject, excluding from the foregoing clauses (ii) and (iii) such requirements,
defaults, breaches, rights or violations that could not reasonably be expected
to have, individually or in the aggregate, a Company Material Adverse Effect.

     (b) No filing or registration with, notification to, or authorization,
consent or approval of, any government or any agency, court, tribunal,
commission, board, bureau, department, political subdivision or other
instrumentality of any government (including any regulatory or administrative
agency), whether federal, state, multinational (including the European
Community), provincial, municipal, domestic or foreign (each, a

                                       A-8
   83


"Governmental Entity") is required in connection with the execution and delivery
of this Agreement by the Company or the performance by the Company of its
obligations hereunder, except (i) the filing of the Certificate of Merger in
accordance with the DGCL and filings to maintain the good standing of the
Surviving Corporation; (ii) compliance with any applicable requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules
and regulations thereunder (the "HSR Act"), and the antitrust, competition,
foreign investment, or similar laws of any foreign countries or supranational
commissions or boards that require pre-merger notifications or filings with
respect to the Merger (collectively, the "Foreign Merger Laws"); (iii)
compliance with any applicable requirements of the Securities Act and the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder (the "Exchange Act"); (iv) compliance with any applicable
requirements of state blue sky or takeover laws; and (v) such other consents,
approvals, orders, authorizations, notifications, registrations, declarations
and filings the failure of which to be obtained or made could not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect.


     SECTION 3.4  Capitalization. The authorized capital stock of the Company
consists of 100,000,000 shares of Common Stock, par value $0.01 per share, of
the Company (the "Common Stock") and 10,000,000 shares of preferred stock, par

to acquire from the Company, and no obligation of the Company to issue, any
capital stock, voting securities or securities convertible into or exchangeable
for capital stock or voting securities of the Company (the items in clauses (v),
(vi) and (vii) being referred to collectively as the "Company Securities"). To
the knowledge of the Company, as of the date of this Agreement, there are not
any agreements that relate to the voting or control of Company Securities. There
are no outstanding obligations of the Company or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any Company Securities. No Subsidiary of
the Company owns any capital stock or other voting securities of the Company.
Schedule 3.4 of the Company Disclosure Schedule sets forth a complete and
accurate list of all stock options, warrants, and other rights to acquire Common
Stock (other than rights outstanding under the Rights Plan), including the name
of the holder, the date of grant, acquisition price, number of shares,
exercisability schedule, termination date, and, in the case of options, the type
of option under the Code. No consent of holders of any such rights, including
participants under the Company's Option Plans or the ESPP, is required to carry
out the provisions of Section 1.5. All actions, if any, required to allow for
the treatment of Company Options, Units and the ESPP as is provided in Section
1.5 have been, or prior to the Closing will be, validly taken by the Company. In
no event will the aggregate number of shares of Common Stock outstanding at the
Effective Time (including all shares subject to then outstanding Company Options
or other rights to acquire or commitments to issue shares of Company stock)
exceed the sum of the outstanding shares of Company Common Stock described in
the first sentence of this Section 3.4, plus any shares of Company Common Stock
issued upon the exercise of outstanding options to purchase Company Common Stock
identified in this Section 3.4, plus any shares of

                                       A-9
   84

Company Common Stock issued by the Company in connection with the Units, plus
any shares of Company Common Stock issued by the Company upon exercise of rights
under the ESPP.

     SECTION 3.5  Subsidiaries.

     (a) Each Subsidiary of the Company (i) is a corporation duly incorporated,
validly existing and in good standing under the laws of its jurisdiction of
incorporation, (ii) has all corporate powers and all material Licenses required
to carry on its business as now conducted, and (iii) is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except for failures of this
representation and warranty to be true which could not reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect. All
Subsidiaries of the Company and their respective jurisdictions of incorporation
are identified in Schedule 3.5 of the Company Disclosure Schedule.

     (b) All of the outstanding shares of capital stock of each Subsidiary of
the Company are duly authorized, validly issued, fully paid and nonassessable,
and such shares are owned by the Company or by a Subsidiary of the Company
(other than, if necessary, shares constituting directors' qualifying shares or
similar shares and shares required to be owned by citizens of such subsidiary's
jurisdiction of organization) free and clear of any Liens (as defined hereafter)
or limitations on voting rights. There are no subscriptions, options, warrants,
calls, rights, convertible securities or other agreements or commitments of any
character relating to the issuance, transfer, sale, delivery, voting or
redemption (including any rights of conversion or exchange under any outstanding
security or other instrument) for any of the capital stock or other equity
interests of any of such Subsidiaries. There are no agreements requiring the
Company or any of its Subsidiaries to make contributions to the capital of, or
lend or advance funds to, any Subsidiaries of the Company. For purposes of this
Agreement, "Lien" means, with respect to any asset, any mortgage, lien, pledge,
charge, security interest, assessment, claim, third party interest or
encumbrance of any kind in respect of such asset.

     SECTION 3.6  SEC Documents. Since December 31, 1998, the Company has filed
all required reports, proxy statements, registration statements, forms and other
documents required to be filed with the SEC (the "Company SEC Documents"). As of
their respective dates, and giving effect to any amendments thereto, (a) the
Company SEC Documents complied in all material respects with the requirements of
the Securities Act or the Exchange Act, as the case may be, and the applicable
rules and regulations of the SEC promulgated thereunder and (b) none of the
Company SEC Documents contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.

     SECTION 3.7  Financial Statements. The financial statements of the Company
(including, in each case, any notes and schedules thereto) included in the
Company SEC Documents (a) were prepared from the books and records of the
Company and its Subsidiaries, (b) comply as to form in all material respects
with all applicable accounting requirements and the rules and regulations of the

SEC under the Exchange Act) during the periods involved and (d) fairly present,
in all material respects, the consolidated financial position of the Company and
its consolidated Subsidiaries as of the dates thereof and the consolidated
results of their operations and cash flows for the periods then ended (subject,
in the case of unaudited statements, to normal year-end audit adjustments which
were not and are not expected to be, individually or in the aggregate, material
in amount). The statements of earnings included in the audited or unaudited
interim financial statements in the Company SEC Documents do not contain any
material items of special or nonrecurring income or any other income not earned
in the ordinary course of business required to be disclosed separately in
accordance with GAAP, except as expressly specified in the applicable statement
of operations or notes thereto.

     SECTION 3.8  Absence Of Undisclosed Liabilities. Neither the Company nor
any of its Subsidiaries has any liabilities or obligations of any nature
(whether accrued, absolute, contingent or otherwise) except (i) liabilities or
obligations that are accrued or reserved against in the audited consolidated
balance sheet of the Company as of December 29, 2000 contained in the Company's
Annual Report on Form 10-K for the

                                       A-10

the unaudited consolidated balance sheet of the Company as of March 30, 2001

notes thereto; (ii) liabilities or obligations incurred in the ordinary course
of business and of a type and in an amount consistent with past practice, since
March 30, 2001; and (iii) liabilities or obligations that could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect.

     SECTION 3.9  Proxy Statement. None of the information contained in the
proxy statement to be filed with the SEC by the Company pursuant to Section 5.3
hereof (the "Proxy Statement") will, as of the date mailed to the stockholders
of the Company, as of the time of the stockholders meeting of the Company (the
"Company Stockholders' Meeting") in connection with the transactions
contemplated hereby and as of the Effective Time, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Proxy Statement
will comply as to form in all material respects with the provisions of the
Exchange Act and the rules and regulations promulgated by the SEC thereunder.
Notwithstanding the foregoing, the Company makes no representation or warranty
with respect to any information supplied by Parent or Merger Sub for inclusion
in the Proxy Statement.

     SECTION 3.10  Absence Of Material Adverse Changes, Etc. Since December 29,
2000, there has not been any change, effect, event, occurrence, state of facts

     outstanding shares of capital stock or other equity securities of, or other
     ownership interests in, the Company or of any Company Securities;

          (b) any amendment of any provision of the Certificate of Incorporation

and each affiliated, combined, consolidated or unitary group of which the
Company or any of its Subsidiaries is a member (a "Company Group") have been

extent any failure to file or any inaccuracies in filed returns could not
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect; (2) all Taxes (as defined below) due and owing by the
Company, any Subsidiary of the Company or any Company Group have been paid, and
all Taxes that have accrued but which are not yet due and owing have been
adequately reserved for in the Company Audited Balance Sheet or the Company
Interim Balance Sheet in accordance with GAAP, except to the extent any failure

Taxes arising in the ordinary course of business after the date of the Company
Interim Balance Sheet; (3) there is no presently pending or, to the knowledge of

Taxes due and owing by the Company, any Subsidiary of the Company or any Company
Group; (4) neither the Company nor any Subsidiary of the Company has filed any
waiver of the statute of limitations applicable to the assessment or collection

except where the failure to be in compliance could not reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect; (8)
neither the Company, any Subsidiary of the Company, nor any Company Group member
is a party to any agreement, contract, arrangement or plan that has resulted or
would result, individually or in the aggregate, in connection with this
Agreement or any change of control of the Company, any Subsidiary of the
Company, or any Company Group member in the payment of any "excess parachute
payments" within the meaning of Section 280G of the Code; and (9) neither the
Company, any Subsidiary of the Company, nor any Company Group Member has made

compensation upon exercise of an option), that would not be fully deductible by
reason of Section 162(m) of the Code.

     SECTION 3.12  Employee Benefit Plans.

     (a) Except for any plan, fund, program, agreement or arrangement that is
subject to the laws of any jurisdiction outside the United States, Schedule
3.12(a) of the Company Disclosure Schedule contains a true and complete list of
each deferred compensation, incentive compensation, and equity compensation
plan; each "welfare" plan, fund or program (within the meaning of Section 3(1)
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"));
each "pension" plan, fund or program (within the meaning of Section 3(2) of
ERISA); each employment, termination or severance agreement; and each other
employee benefit plan, fund, program, agreement or arrangement that is
sponsored, maintained or contributed to or required to be contributed to by the
Company, any Subsidiary of the Company, or by any trade or business, whether or
not incorporated (each, an "ERISA Affiliate"), that together with the Company
would be deemed a "single employer" within the meaning of Section 4001(b) of
ERISA, or to which the Company, any Subsidiary of the Company, or an ERISA
Affiliate is party, whether written or oral, for the benefit of any employee,
consultant, director or former employee, consultant or director of the Company
or any Subsidiary of the Company. The plans, funds, programs, agreements and
arrangements listed on Schedule 3.12(a) of the Company Disclosure Schedule are
referred to herein collectively as the "Plans."

     (b) With respect to each Plan, the Company has heretofore delivered or made
available to Parent true and complete copies of the Plan and any amendments
thereto (or if the Plan is not a written Plan, a description thereof), any
related trust or other funding vehicle, the most recent reports or summaries
required under ERISA or the Code and the most recent determination letter
received from the Internal Revenue Service with respect to each Plan intended to
qualify under Section 401 of the Code.

     (c) No liability under Title IV or Section 302 of ERISA or Section 412 of
the Code has been incurred by the Company or any ERISA Affiliate that has not
been satisfied in full, other than liability for premiums due the Pension
Benefit Guaranty Corporation (which premiums have been paid when due).

     (d) No Plan is a "multiemployer plan," as defined in Section 3(37) of
ERISA, nor is any Plan a plan described in Section 4063(a) of ERISA. Neither the
Company nor any ERISA Affiliate maintains, participates in, contributes to, or
has any obligation to contribute or any liability with respect to any multiple
employer or multiemployer plan, or has had any obligation with respect to such a
plan.

     (e) Each Plan has been operated and administered in all material respects
in accordance with its terms and applicable law, including ERISA and the Code.

     (f) Each Plan intended to be "qualified" within the meaning of Section
401(a) of the Code has received a favorable determination letter from the
Internal Revenue Service, or in the case of such a Plan for which a favorable
determination letter has not yet been received, the applicable remedial
amendment period under Section 401(b) of the Code has not expired.

     (g) No Plan provides medical, surgical, hospitalization, death or similar
benefits (whether or not insured) for employees or former employees of the
Company or any Subsidiary for periods extending beyond their retirement or other
termination of service, other than (i) coverage mandated by applicable law, (ii)
death benefits under any "pension plan," or (iii) benefits the full cost of
which is borne by the current or former employee (or his or her beneficiary),
dependant or other covered person.

     (h) There are no pending, or to the knowledge of the Company, threatened or
anticipated, claims that could reasonably be expected to have, individually or
in the aggregate, a Company Material Adverse Effect by or on behalf of any Plan,
or by any employee or beneficiary covered under any such Plan (other than
routine claims for benefits). No event has occurred and, to the knowledge of the
Company, there exists no condition or set of circumstances in connection with
which the Company or any of its Subsidiaries would be subject to any liability
under the terms of such Plans (other than the payment of benefits thereunder),
ERISA, the Code

                                       A-13
   88

or any other applicable law that could reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect.

     (i) The consummation of the transactions contemplated by this Agreement
will not, either alone or in combination with another event, (i) entitle any
current or former employee or officer of the Company or any ERISA Affiliate to
severance pay, unemployment compensation or any other payment, except as
expressly provided in this Agreement, or (ii) accelerate the time of payment or
vesting, or increase the amount of compensation due any such employee or
officer, other than payments, accelerations or increases (x) under any employee
benefit plan that is subject to the laws of a jurisdiction outside of the United
States or (y) mandated by applicable law or the terms of the Plans.

     (j) No amounts payable under the Plans will fail to be deductible for
federal income tax purposes by virtue of Section 280G of the Code.

     (k) To the knowledge of the Company, all employee benefit plans that are
subject to the laws of any jurisdiction outside the United States are in
material compliance with such applicable laws, including relevant Tax laws, and
the requirements of any trust deed under which they were established, except for
such exceptions to the foregoing which, in the aggregate, could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. Schedule 3.12(k) lists all material employee pension benefit
plans that are subject to the laws of any jurisdiction outside the United
States.

     (l) Each Plan can be amended prospectively or terminated at any time,
without advance notice, and without any liability other than for benefits
accrued prior to such amendment or termination (other than administrative
charges normally incurred in a plan termination).

     (m) No agreement, commitment, or obligation exists to increase any benefits
under any Plan or to adopt any new Plan.

     (n) No Plan has any unfunded accrued benefits that are not fully reflected
in the Company Audited Balance Sheet.

     (o) No pension plan subject to Title IV of ERISA (an "ERISA Pension Plan")
has incurred any "accumulated funding deficiency" or "waived funding deficiency"
within the meaning of Section 302 of ERISA or Section 412 of the Code and
neither the Company nor any Subsidiary of the Company has ever sought to obtain
any variance from the minimum funding standards pursuant to Section 412(d) of
the Code. The funding method used in connection with each ERISA Pension Plan
meets the requirements of ERISA and the Code and the actuarial assumptions used
in connection with each such plan are reasonable, given the experience of such
ERISA Pension Plan and reasonable expectations.

     (p) The fair market value of the plan assets of each ERISA Pension Plan are
at least equal to (i) the present value of its benefit liabilities (as defined
in ERISA Section 4001(a)(16)), including any unpredictable contingent event
benefits within the meaning of Code Section 412(l)(7), and determined on the
basis of assumptions prescribed by the PBGC for purposes of ERISA Section 4044),
and (ii) the Projected Benefit Obligations thereunder, as defined in Statement
of Financial Accounting Standards No. 87, including any allowance for indexation
and ad hoc increases. No ERISA Pension Plan has been completely or partially
terminated or been the subject of a Reportable Event under ERISA Section 4043.
No proceeding by the PBGC to terminate any ERISA Pension Plan has been
instituted, and neither the Company nor any Subsidiary of the Company has
incurred any liability to the PBGC (other than the PBGC premiums, all of which
have been timely paid) or otherwise under Title IV of ERISA with respect to any
ERISA Pension Plan.

     (q) Neither the Company nor any Subsidiary of the Company maintains or
participates in any Voluntary Employees' Beneficiary Association, under Code
Sections 419 and 419A, which is intended to be exempt from taxation under
section 501(c)(9) of the Code.

     SECTION 3.13  Litigation; Compliance With Laws.

     (a) There is no claim, action, suit, proceeding or, to the knowledge of the
Company, investigation or review of any kind pending, or to the knowledge of the
Company, threatened against the Company or any Subsidiary of the Company or any
of their respective properties or any of their respective officers or directors
in their capacity as officers or directors of the Company or of any Subsidiary
of the Company which could reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect.

     (b) Neither the Company nor any Subsidiary of the Company is in default or
violation of any applicable federal, state, local, or foreign laws, ordinances,
regulations, interpretations, judgments, decrees, injunctions, permits,
licenses, certificates, governmental requirements, orders, or other
promulgations, of any court or other Governmental Entity (and including those of
any nongovernmental self-regulatory agency and including environmental laws or
regulations), except for such defaults or violations that could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. The Company and each Subsidiary of the Company has timely filed
or otherwise provided all registrations, reports, data, and other information
and applications with respect to its medical device, pharmaceutical, consumer,
health care, and other governmentally regulated products (the "Regulated
Products") required to be filed with or otherwise provided to the FDA or any
other Governmental Entity with jurisdiction over the manufacture, use, or sale
of the Regulated Products, has complied with all applicable requirements of the
FDA or other Governmental Entity with respect to the Regulated Products, and all
regulatory licenses or approvals in respect thereof are in full force and
effect, except where the failure to file timely such registrations, reports,
data, information, and applications or to be in compliance or the failure to
have such licenses and approvals in full force and effect could not reasonably
be expected to have, individually or in the aggregate, a Company Material
Adverse Effect. All documentation, correspondence, reports, data, analyses and
certifications relating to or regarding any medical devices of the Company or
any Subsidiary of the Company, filed with or delivered by or on behalf of the
Company or any Subsidiary of the Company to any Governmental Entity was in all
material respects true and accurate when so filed or delivered and, to the
knowledge of the Company, remains true and accurate. All governmental approvals,
permits and licenses (collectively, "Permits") required to conduct the business
of the Company and its Subsidiaries as it is currently being conducted have been
obtained, are in full force and effect and are being complied with, except where
such failure could not reasonably be expected to have a Company Material Adverse
Effect.

     SECTION 3.14  Labor Matters. (i) There is no labor strike, dispute,
slowdown, stoppage or lockout actually pending or, to the knowledge of the
Company, threatened against the Company or any Subsidiary of the Company; (ii)
to the knowledge of the Company, no union organizing campaign with respect to
employees of the Company or any Subsidiary of the Company is underway; (iii)
there is no unfair labor practice charge or complaint against the Company or any
Subsidiary of the Company pending or, to the knowledge of the Company,
threatened before the National Labor Relations Board or any similar state or
foreign agency; (iv) there is no written grievance pending relating to any
collective bargaining agreement or other grievance procedure to which the
Company or any Subsidiary of the Company is a party or subject; (v) to the
knowledge of the Company, no charges with respect to or relating to the Company
or any Subsidiary of the Company are pending before the Equal Employment
Opportunity Commission or any other agency responsible for the prevention of
unlawful employment practices; and (vi) there are no collective bargaining
agreements with any union covering employees of the Company or any Subsidiary of
the Company, except for such exceptions to the foregoing clauses (i) through
(vi) which could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect.

     SECTION 3.15  Certain Contracts And Arrangements. Schedule 3.15 of the
Company Disclosure Schedule lists, and the Company has heretofore furnished to
Parent complete and accurate copies of (or, if oral, the Company Disclosure
Schedule states all material provisions of), (a) every employment, material
consulting, severance or change of control agreement or arrangement for the
benefit of any director, officer, employee, other person or stockholder of the
Company or any Subsidiary of the Company or any affiliate thereof in effect as
of the date of this Agreement to which the Company or any Subsidiary of the
Company is a party or by which the Company or any Subsidiary of the Company or
any of their properties or assets is bound, (b) every material contract with
physicians, scientific advisory board members or material consultants in

                                       A-15
   90

effect as of the date of this Agreement to which the Company or any Subsidiary
of the Company is a party or by which the Company or any Subsidiary of the
Company or any of their properties or assets is bound, and (c) every contract,
agreement, or understanding to which the Company or any Subsidiary of the
Company is a party that would reasonably be expected to involve payments by or
to the Company or any Subsidiary of the Company in excess of $500,000 during the
Company's current 2001 fiscal year, or the absence or performance of which could
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect, or that is material and was not made in the ordinary
course of business. Each material contract or agreement to which the Company or
any Subsidiary of the Company is a party or by which any of them is bound is in
full force and effect, and neither the Company nor any Subsidiary of the
Company, nor, to the knowledge of the Company, any other party thereto, is in
breach of, or default under, any material contract or material agreement to
which the Company or any Subsidiary of the Company is a party or by which any of
them is bound, and no event has occurred that with notice or passage of time or
both would constitute such a breach or default thereunder by the Company or any
Subsidiary of the Company, or, to the knowledge of the Company, any other party
thereto, except for such breaches and defaults which could not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect. As of the date of this Agreement, neither the Company nor any Subsidiary
of the Company is a party to any contract, plan, agreement, understanding,
arrangement or obligation (i) that restricts the ability of the Company or any
Subsidiary of the Company, or after the Merger would restrict the Surviving
Corporation's or Parent's ability, to conduct any line of business, (ii) that

     (c) The Company shall as promptly as practicable notify (and provide copies
to) Parent of the receipt of any comments from the SEC relating to the Proxy
Statement. All filings by the Company with the SEC in connection with the
transactions contemplated hereby, including the Proxy Statement and any
amendment or supplement thereto, shall be subject to the prior review of Parent,
and all mailings to the Company's stockholders in connection with the
transactions contemplated by this Agreement shall be subject to the prior review
of Parent.

     (d) Unless and until this Agreement is validly terminated pursuant to
Article VII, nothing herein shall limit or eliminate in any way the Company's
obligation to call, give notice of, convene and hold the Company Stockholders'
Meeting and at such meeting submit this Agreement and the Merger to a vote of
the Company's stockholders (and not postpone or adjourn such meeting or the vote
by the Company's stockholders upon this Agreement and the Merger to another date
without Parent's approval).

     SECTION 5.4  Access To Information; Confidentiality Agreement

     (a) Except as required pursuant to any confidentiality agreement or similar
agreement or arrangement to which the Company or any of the Company's
Subsidiaries is a party (in which case the Company shall use all commercially
reasonable efforts to provide acceptable alternative arrangements, not in
violation of such agreement or arrangement, for disclosure to Parent or its
advisors) or pursuant to applicable law or the regulations or requirements of
any stock exchange or other regulatory organization with whose rules the Company
is required to comply, from the date of this Agreement to the Effective Time,
the Company shall (and shall direct its Subsidiaries to) (i) provide to Parent
(and its officers, directors, employees, accountants, consultants, legal
counsel, agents and other representatives (collectively, "Representatives"))
access at reasonable times during normal business hours in a manner so as not to
unreasonably disrupt the ordinary course of business upon prior written notice
to its and its Subsidiaries' officers, employees, agents, properties, offices
and other facilities and to the books and records thereof, and (ii) furnish
promptly to Parent all information concerning the Company's and its
Subsidiaries' businesses, prospects, properties, liabilities, results of
operations, financial condition, product evaluations and testing, pilot studies,
clinical data and studies and evaluations, patient results, regulatory
compliance, officers, employees, third party physicians and clinical
investigators, consultants, distributors, customers, suppliers, and others
having material dealings with the Company as Parent may reasonably request and
reasonable opportunity to contact and obtain information

                                       A-23
   98

from such officers, employees, investigators, consultants, distributors,
customers, suppliers, and others having dealings with the Company as Parent may
reasonably request. Subject to the foregoing provisions, the Company's
obligation to afford access and provide information pursuant to the preceding
sentence shall include such access and information as Parent shall reasonably
deem necessary to enable Parent, or a third party designated by Parent and
approved by the Company, to conduct a reasonable audit of the Company's and its
Subsidiaries' product performance and quality, pilot studies, clinical data and
results, patient results, compliance with FDA regulations, policies and
procedures, relations and dealings with third party physicians and other
clinical investigators and consultants, and related performance and compliance
matters concerning the Company's and its Subsidiaries' products. During the
period from the date hereof to the Effective Time, the parties shall in good
faith meet and correspond on a regular basis for mutual consultation concerning
the conduct of the Company's and its Subsidiaries' businesses and, in connection
therewith, Parent shall be entitled to be kept informed concerning, the
Company's and its Subsidiaries' operations and business planning. No
investigation conducted pursuant to this Section 5.4 shall affect or be deemed
to modify any representation or warranty made in this Agreement or modify or
expand the conditions to closing set forth in Article VI. Nothing in this
Agreement will require disclosure prior to the Effective Time of minutes,
reports, or documents related to the Special Committee.

     (b) Parent and each of its employees and other representatives shall hold
in confidence all such nonpublic information as required and in accordance with
the confidentiality agreement between Parent and the Company dated April 26,
2000 (the "Confidentiality Agreement").

     SECTION 5.5  No Solicitation.

     (a) The Company shall not (whether directly or indirectly through advisors,
agents or other intermediaries), and the Company shall cause its respective
officers, directors, advisors, representatives or other agents (including any
investment banker, attorney, or accountant retained by the Company or any
Subsidiary) not to, directly or indirectly, (1) solicit, initiate or knowingly
encourage any Acquisition Proposal (as defined hereafter) or (2) participate in
or encourage in any way discussions or negotiations with, or provide any
nonpublic information to, any corporation, partnership, person, or other entity
or group (other than Parent or any affiliate or agent of Parent) concerning any
Acquisition Proposal, or otherwise facilitate any effort or attempt to make or
implement an Acquisition Proposal; provided, however, that, notwithstanding the
foregoing provisions of this Section 5.5, this Agreement shall not prohibit the
Company's Special Committee from, prior to the date on which the Company's
stockholders adopt this Agreement in accordance with the DGCL, furnishing
nonpublic information to or entering into discussions or negotiations with, any
person or entity that makes an unsolicited Superior Proposal, if, and only to
the extent that, (i) the failure of the Company's Board of Directors to take
action with respect to a Superior Proposal would be a breach of the Board's
fiduciary duties to its shareholders imposed by applicable law; (ii) prior to
first furnishing nonpublic information to, or first entering into substantive
discussions and negotiations with, such person or entity after the date hereof,
the Company (A) provides written notice of at least five business days to Parent
to the effect that it intends to furnish information to, or enter into
discussions or negotiations with, such person or entity, and naming and
identifying the person or entity making the Acquisition Proposal, and (B)
receives from such person or entity an executed confidentiality agreement with
terms no less favorable to the Company than the Confidentiality Agreement (as
defined in Section 5.4(b)) entered into with Parent; and (iii) the Company
concurrently provides Parent with all non-public information to be provided to
such person or entity that Parent has not previously received from the Company,
and the Company keeps Parent informed, on a daily or more regular basis if the
context requires or Parent so requests, of the status, terms and conditions and
all other material information with respect to any such discussions or
negotiations.

     (b) For purposes of this Agreement, "Acquisition Proposal" means any offer
or proposal for any of the following involving the Company or any Subsidiary of
the Company: (i) any tender offer, exchange offer, merger, consolidation, share
exchange, business combination or similar transaction involving more than fifty
percent of capital stock of the Company or any Subsidiary of the Company; (ii)
any transaction or series of related transactions pursuant to which any person
or entity (or its stockholders), other than Parent, or Merger Sub or any of
their affiliates (a "Third Party") acquires shares (or securities exercisable
for or convertible into shares) representing more than fifty percent of the
outstanding shares of any class of capital stock of the

                                       A-24
   99

Company or any Subsidiary of the Company; or (iii) any sale, lease, exchange,
licensing, transfer or other disposition pursuant to which a Third Party
acquires control of more than 20% of the assets (including, but not limited to,
intellectual property assets) of the Company and its Subsidiaries taken as a
whole (determined by reference to the fair market value of such assets), in a
single transaction or series of related transactions.

     (c) As used herein, a "Superior Proposal" shall mean a bona fide
Acquisition Proposal (i) that the Company's Special Committee has reasonably and
in good faith determined (with the advice of its financial advisors and taking
into account all material legal, financial and regulatory aspects of such
Acquisition Proposal) to be more favorable to the Company's stockholders than
the transactions contemplated by this Agreement; and (ii) with respect to which
the financing required to consummate the transaction contemplated by such
Acquisition Proposal is committed or in the good faith determination of the
Company's Special Committee, after consultation with its financial advisor, is
likely to be obtained on a timely basis.

     (d) The Company will immediately terminate all discussions with Third
Parties concerning any Acquisition Proposal, and will request that such Third
Parties promptly return any confidential information furnished by the Company in
connection with any Acquisition Proposal. Subject to this Section 5.5, the
Company will not waive any provision of any confidentiality, standstill or
similar agreement entered into with any Third Party regarding any Acquisition
Proposal, and prior to the Closing shall enforce all such agreements in
accordance with their terms. The Company will promptly communicate to Parent the
name of the person or entity submitting, and a detailed description of the terms
and conditions of, any proposal or inquiry that it receives after the date
hereof in respect of any Acquisition Proposal or a reasonably detailed
description of any such information requested from it after the date hereof or
of any such negotiations or discussions being sought to be initiated or
continued with the Company after the date hereof in respect of an Acquisition
Proposal.

     (e) Nothing contained in this Section 5.5 shall (i) permit the Company to
terminate this Agreement (except as specifically provided in Article VII
hereof), or (ii) permit the Company to enter into any agreement providing for an
Acquisition Proposal (other than the confidentiality agreement as provided, and
in the circumstances and under the conditions set forth, above) for as long as
this Agreement remains in effect.

     (f) Nothing contained in this Section 5.5 shall prohibit the Company or the
Company's Board of Directors from taking and disclosing to the Company's
stockholders a position with respect to a tender or exchange offer by a third
party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or
from making any disclosure required by applicable law.

     SECTION 5.6  Director And Officer Liability.

     (a) Parent and the Company agree that all rights to indemnification and
advancement of expenses and all limitations on liability existing in favor of
any Indemnitee (as defined hereafter) as provided in the Certificate of
Incorporation or Bylaws of the Company existing on the date of this Agreement
shall survive the Merger and continue in full force and effect in accordance
with its terms for at least six years after the Effective Time, unless
modification of such rights or limitations is required by law.

     (b) For six years after the Effective Time, Parent shall or shall cause the
Surviving Corporation to indemnify and hold harmless, and to advance expenses
to, the individuals who on or prior to the Effective Time were officers,
directors, employees or agents of the Company (the "Indemnitees") to the full
extent permitted by applicable law. In the event any claim in respect of which
indemnification is available pursuant to the foregoing provisions is or may be
asserted or made within such six-year period, all rights to indemnification and
advancement of expenses shall continue until such claim is disposed of or all
judgments, orders, decrees or other rulings in connection with such claim are
fully satisfied.

     (c) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the Company
pursuant to each indemnification agreement that is described in Schedule 5.6 of
the Company Disclosure Schedule and is in effect at the Effective Time. Parent
shall guarantee the obligations of the Surviving Corporation with respect to the
indemnification and payment of fees and expenses provisions contained in the
Surviving Corporation's Certificate of Incorporation and Bylaws with

                                       A-25
   100

respect to acts occurring at or before the Effective Time (including the
transactions contemplated by this Agreement).

     (d) For a period of three years after the Effective Time, Parent shall, at
its selection, either: (i) cause to be maintained in effect the Company's
current directors' and officers' liability insurance policy (a copy of which has
been heretofore delivered or made available to Parent or its advisors) with
respect to claims arising from facts or events that occurred at or prior to the
Effective Time; or (ii) extend the discovery or reporting period under the
Company's current policy for three years from the Effective Time to maintain in
effect directors' and officers' liability insurance with respect to claims
arising from facts or events that occurred at or prior to the Effective Time for
those persons who are currently covered by the Company's directors' and
officers' liability insurance policy on terms no less favorable than the terms
of such current insurance policy; or (iii) substitute coverage under Parent's
directors' and officers' liability insurance or coverage under other policies
providing coverage on terms and conditions that are no less advantageous to such
persons than the Company's current insurance with respect to claims arising from
facts or events that occurred at or prior to the Effective Time; provided,
however, that in no event shall Parent be required to expend for any such
coverage an amount per year in excess of 150% of the annual premium currently
paid by the Company for such insurance; and provided further that if the cost
per year of such coverage exceeds such 150% amount, Parent shall be obligated to
obtain such coverage as is available for a cost per year not exceeding such
amount. The Company represents that the Company Disclosure Schedule sets forth
the annual premium currently paid by the Company for such insurance.

     (e) In the event Parent, the Surviving Corporation or any of their
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then and in each such case, proper
provisions shall be made so that the successors and assigns of Parent or the
Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.6.

     (f) This Section 5.6 shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, Parent, the Surviving
Corporation and the Indemnitees, and shall be binding on all successors and
assigns of Parent and the Surviving Corporation.

     SECTION 5.7  Commercially Reasonable Efforts. Upon the terms and subject to
the conditions of this Agreement, each party hereto shall use commercially
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate the transactions contemplated by this
Agreement.

     SECTION 5.8  Consents; Certain Filings.

     (a) The Company and Parent shall cooperate with one another (i) in
connection with the preparation of the Proxy Statement, (ii) in determining
whether any action by or in respect of, or filing with, any Governmental Entity
is required, or any actions, consents, approvals or waivers are required to be
obtained from parties to any material contracts, in connection with the
consummation of the transactions contemplated by this Agreement and (iii) in
seeking any such actions, consents, approvals or waivers or making any such
filings, furnishing information required in connection therewith or with the
Proxy Statement and seeking timely to obtain any such actions, consents,
approvals or waivers.

     (b) Without limiting the provisions of this Section 5.8, each party hereto
shall, if applicable, file with the Department of Justice and the Federal Trade
Commission a Pre-Merger Notification and Report Form pursuant to the HSR Act in
respect of the transactions contemplated hereby as soon as reasonably
practicable, and each party will use commercially reasonable efforts to take or
cause to be taken all actions necessary, including to promptly and fully comply
with any requests for information from regulatory Governmental Entities, to
obtain any clearance, waiver, approval or authorization relating to the HSR Act
that is necessary to enable the parties to consummate the transactions
contemplated by this Agreement. Without limiting the provisions of this Section
5.8, each party hereto shall use commercially reasonable efforts to promptly
make the filings required to be made by it with all foreign Governmental
Entities in any jurisdiction in which the parties believe it is necessary or
advisable.

                                       A-26
   101

     (c) The Company and Parent shall each use commercially reasonable efforts
to resolve such objections, if any, as may be asserted with respect to the
Merger or any other transaction contemplated by this Agreement under any
Antitrust Law (as defined below). If any administrative, judicial or legislative
action or proceeding is instituted (or threatened to be instituted) challenging
the Merger or any other transaction contemplated by this Agreement as violative
of any Antitrust Law, the Company and Parent shall each cooperate to contest and
resist any such action or proceeding, and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order (whether temporary,
preliminary or permanent) that is in effect and that restricts, prevents or
prohibits consummation of the Merger or any other transaction contemplated by
this Agreement, including, without limitation, by pursuing all reasonable
avenues of administrative and judicial appeal. Notwithstanding anything to the
contrary in this Agreement, none of Parent, any of its Subsidiaries or the
Surviving Corporation, shall be required (and the Company shall not, without the
prior written consent of Parent, agree, but shall, if so directed by Parent,
agree, effective after the Effective Time) to hold separate or divest any of
their respective assets or operations or enter into any consent decree or
licensing or other arrangement with respect to any of their assets or operations
or to otherwise take or commit to take any action that limits its freedom of
action with respect to, or its ability to retain, as of and after the Effective
Time any businesses or assets of the Company, Parent or any of their respective
affiliates.

     (d) Each of the Company and Parent shall promptly inform the other party of
any material communication received by such party from the Federal Trade
Commission, the Antitrust Division of the Department of Justice or any other
governmental or regulatory authority regarding any of the transactions
contemplated hereby.

     (e) The Company will, at its cost and expense, use all reasonable efforts
to obtain all approvals and consents of all third parties necessary on the part
of the Company or its Subsidiaries to promptly consummate the transactions
contemplated hereby. Parent agrees to cooperate with the Company in connection
with obtaining such approvals and consents. Parent will, at its cost and
expense, use all reasonable efforts to obtain all approvals and consents of all
third parties necessary on the part of Parent or Merger Sub to promptly
consummate the transactions contemplated hereby. The Company agrees to cooperate
with Parent in connection with obtaining such approvals and consents.

     (f) "Antitrust Law" means the Sherman Act, as amended, the Clayton Act, as
amended, and all other federal, state and foreign statutes, rules, regulations,
orders, decrees, administrative and judicial doctrines, and other laws that are
designed or intended to prohibit, restrict or regulate competition or actions
having the purpose or effect of monopolization or restraint of trade.

     SECTION 5.9  Public Announcements. The parties shall issue press releases
in agreed upon form announcing the execution of this Agreement as soon as
practicable on or after the date hereof. Neither the Company, Parent nor any of
their respective affiliates shall issue or cause the publication of any press
release or other public announcement with respect to the Merger, this Agreement
or the other transactions contemplated hereby without the prior written consent
of the other party, except as may be required by law or by any listing agreement
with, or the policies of, a national securities exchange or the NASDAQ National
Market.

     SECTION 5.10  Further Assurances. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Merger Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the name
and on behalf of the Company or Merger Sub, any other actions to vest, perfect
or confirm of record or otherwise in the Surviving Corporation any and all
right, title and interest in, to and under any of the rights, properties or
assets of the Company acquired or to be acquired by the Surviving Corporation,
as a result of, or in connection with, the Merger.

     SECTION 5.11  Employee Matters.

     (a) From and after the Effective Time, Parent shall to the extent
practicable cause the Surviving Corporation to provide employee benefits and
programs to the Company's employees that, in the aggregate, are substantially
comparable or more favorable, as a whole, than those in existence as of the date
hereof and

                                       A-27
   102

disclosed in writing to Parent prior to the execution hereof; provided that
stock-based compensation shall be comparable to that offered by Parent and its
subsidiaries generally. To the extent Parent satisfies its obligations under
this Section by maintaining Company benefit plans, Parent shall not be required
to include employees of the Company in Parent's benefit plans.

     (b) Parent shall, or shall cause the Company to, give individuals who are
employed by the Company or any of its Subsidiaries as of the Effective Time and
who remain employees of the Company or such Subsidiary following the Effective
Time (each such employee, an "Affected Employee") full credit to the extent each
such Affected Employee has been credited with service under each comparable
employee benefit plan or arrangement maintained by the Company immediately prior
to the Effective Time for purposes of eligibility, level of participation and
vesting under each employee benefit plan or arrangement maintained by Parent or
the Company for such Affected Employee's service with the Company.

     (c) Under no circumstances shall employees receive credit for service
accrued or deemed accrued prior to the Effective Time with the Company or such
Subsidiary, as the case may be, for benefit accruals under any employee pension
benefit plan (as defined by Section 3(2) of ERISA) or any retiree health plan.

     SECTION 5.12  State Takeover Laws. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation is or may become applicable to the Merger, the Company shall take
such actions as are necessary so that the transactions contemplated by this
Agreement may be consummated as promptly as practicable on the terms
contemplated hereby and otherwise act to eliminate or minimize the effects of
any such statute or regulation on the Merger.

     SECTION 5.13  Certain Notifications. Between the date hereof and the
Effective Time, the Company and Parent shall each promptly notify the other in
writing after becoming aware of the occurrence of any event which will, or is
reasonably likely to, result in the failure to satisfy any of the conditions to
such other party's obligations specified in Article VI.

     SECTION 5.14  Voting of Shares. To induce Parent to execute this Agreement,
certain officers and directors of the Company have executed and delivered as of
the date hereof Agreements to Facilitate Merger in the form attached hereto as
Exhibit B, pursuant to which each such person has agreed to vote all of his or
her shares of Common Stock in favor of the adoption of this Agreement. To the
extent not already delivered to Parent, the Company will use reasonable best
efforts to have all other such affiliates execute and deliver to Parent
Agreements to Facilitate Merger as soon as practicable after the date hereof.


     SECTION 5.15  Stock Rights. Prior to the Effective Time, the Company shall
obtain all consents and agreements and take any other action required to allow
for the treatment of Company Options, Units and rights pursuant to the ESPP as
is provided in Section 1.5.


     SECTION 5.16  Noncompetition Agreements. To induce Parent to execute this
Agreement, the Company has caused those executives who, as of the date hereof,
have been specified in writing by Parent to execute and deliver to Parent as of
the date hereof (but expressly contingent upon the Closing of the Merger)
noncompetition agreements substantially in the form previously provided to the
Company and attached to such writing. To the extent not already delivered to
Parent, the Company shall use reasonable best efforts to have such other persons
who have been specified in such writing execute and deliver to Parent such
noncompetition agreements as soon as practicable after the date hereof.

     SECTION 5.17  Subsidiary Shares. At or prior to the Closing, the Company
shall use reasonable best efforts to cause all issued and outstanding shares of
capital stock of the Company's Subsidiaries (other than any interests in joint
ventures or similar arrangements) owned by any person other than the Company or
any of its Subsidiaries to be transferred, effective at the Effective Time, for
no or nominal consideration to such person or persons designated by Parent.

     SECTION 5.18  MRG Transaction.

     (a) Parent will not consummate the transactions contemplated under the
Agreement and Plan of Merger dated of even date herewith (the "MRG Agreement")
between Parent and Medical Research Group, Inc. ("MRG") prior to the Effective
Time unless this Agreement has been terminated in a manner that results or

                                       A-28
   103

could (with the passage of time or occurrence of events) result in the
Termination Fee being paid or payable pursuant to Section 7.3.

     (b) Parent will not amend or modify the MRG Agreement or waive any rights
thereunder in a manner that would reasonably be expected to prevent or delay the
Effective Time or the timely closing under the MRG Agreement.

                                   ARTICLE VI

     within the United States or the European Union that is then in effect and
     (i) has the effect of making the Merger illegal or otherwise prohibiting
     the consummation of the Merger, or (ii) would impose any material
     limitation on the ability of Parent to effectively exercise full rights of
     ownership of the Company or the assets or business of the Company or its
     Subsidiaries;

     SECTION 6.2  Conditions To The Company's Obligation To Consummate The

                                       A-29
   104

     not reasonably be expected to have, individually or in the aggregate, a

     not reasonably be expected to have, individually or in the aggregate, a
     Company Material Adverse Effect, and Parent and Merger Sub shall have
     received evidence satisfactory to them of the receipt of such permits,
     authorizations, consents, and approvals;

          (e) Since the date of this Agreement, there shall not have occurred or

     development that has had, or could reasonably be expected to have,
     individually or in the aggregate, a Company Material Adverse Effect;

     occurrence, state of facts or development with respect to MRG that, in the
     case of each of clause (A) or (B), has had or could reasonably be expected
     to have, individually or in the aggregate, a Company Material Adverse
     Effect. Solely for purposes of applying the definition of Company Material
     Adverse Effect to this Section 6.3(g), "Company" means the Company and MRG
     taken together as a whole).

          (ii) Upon learning of any fact or circumstance that Parent determines
     would lead to the closing condition set forth in this Section 6.3(g) not
     being met (a "Potential Closing Problem"), Parent will give to the Company
     prompt notice thereof and keep the Company reasonably informed (on a daily
     or more frequent basis if the context requires or the Company so requests)
     of the status, facts, and other material information with respect to any
     such matter; provided that failure to give such notice shall not adversely
     affect Parent's rights except, and only to the extent that, the Company
     demonstrates it has been prejudiced by such failure. Parent will, at the
     Company's request allow the Company and its representatives to be directly
     involved in the discussions or negotiations with respect to any Potential
     Closing Problem, and afford the Company and its representatives a
     reasonable opportunity to actively participate in attempting to resolve the
     Potential Closing Problem in a manner reasonably satisfactory to Parent.

          (h) All applicable waiting periods under the HSR Act or any Foreign
     Merger Law relating to the transactions contemplated by the MRG Agreement
     shall have expired or been terminated.

                                  TERMINATION

     SECTION 7.1  Termination. Notwithstanding anything herein to the contrary,
this Agreement may be terminated and the transactions contemplated by this
Agreement may be abandoned at any time prior to the Closing Date, whether before
or after this Agreement has been adopted by the Company's stockholders:

          (a) by the mutual written consent of the Company and Parent;

          (b) by either the Company or Parent, if the Merger has not been
     consummated by December 31, 2001, or such other date, if any, as the
     Company and Parent shall agree upon; provided, that the party seeking to
     terminate this Agreement pursuant to this Section 7.1(b) shall not have
     breached in any material respect its obligations under this Agreement in
     any manner that shall have been the proximate cause of, or resulted in, the
     failure to consummate the Merger by such date; and provided further,
     however, that, if a request for additional information is received from the
     U.S. Federal Trade Commission ("FTC") or Department of Justice ("DOJ")
     pursuant to the HSR Act or additional information is requested by a
     governmental authority (a "Foreign Authority") pursuant to Foreign Merger
     Laws, such date shall be extended to the later of (i) the date set forth
     above or (ii) the 90th day following acknowledgment by the FTC, DOJ, or
     Foreign Authority, as applicable, that Parent and the Company have complied
     with such request, but in any event not later than March 31, 2002;

          (c) by either Parent or the Company if a court of competent
     jurisdiction or an administrative, governmental, or regulatory authority in
     the United States or the European Union has issued a final nonappealable
     order, decree, or ruling, or taken any other action, having the effect of
     permanently restraining, enjoining, or otherwise prohibiting the Merger;

          (d) by Parent, if (i) the Company has breached its obligations under
     Section 5.5 in any material respect; or (ii) the Board of Directors of the
     Company shall have withdrawn or modified or amended in any respect adverse
     to Parent or Merger Sub its approval or recommendation of the Merger; or
     (iii) the Board of Directors of the Company shall have recommended to the
     stockholders of the Company any Acquisition Proposal or shall have resolved
     or announced an intention to do so; or (iv) a tender offer or exchange
     offer for 50% or more of the outstanding shares of the Company Common Stock
     is announced or commenced and either (A) the Board of Directors of the
     Company recommends acceptance of such tender offer or exchange offer by its
     stockholders or (B) within ten (10) business days of such commencement, the
     Board of Directors of the Company shall have failed to recommend against
     acceptance of such tender offer or exchange offer by its stockholders;

          (e) by either the Company or Parent, if the adoption of this Agreement
     by the Company's stockholders as required under applicable law shall not
     have been obtained at the Company Stockholders' Meeting; except that the
     right to terminate this Agreement under this Section 7.1(e) will not be
     available to any party whose failure to perform any obligation under this
     Agreement has been the proximate cause of, or resulted in, the failure to
     obtain the requisite vote of the stockholders of the Company; or

          (f) by the Company prior to the adoption of this Agreement by the
     Company's stockholders if (i) it has complied with, and continues to comply
     with, all requirements, conditions and procedures of Section 5.5 in all
     material respects, (ii) the Board of Directors of the Company has (upon the
     recommendation of the Company's Special Committee) authorized, subject to
     complying with the terms of this Agreement, the Company to enter into a
     binding written agreement concerning a transaction that constitutes a
     Superior Proposal and the Company notifies Parent in writing that it
     intends to enter into such binding agreement, which notice must have
     attached to it the most current version of such agreement, (iii) Parent
     does not make, within five business days after receipt of such notice from
     the Company, any offer that the Company's Special Committee reasonably and
     in good faith determines, after consultation with its financial and legal
     advisors, is at least as favorable to the stockholders of the Company as
     the Superior Proposal and during such five business-day period the Company
     reasonably considers and discusses in good faith all proposals submitted by
     Parent and, without limiting the foregoing, meets with, and causes its
     financial advisors and legal advisors to meet with, Parent and its

                                       A-31
   106

     advisors from time to time as requested by Parent to reasonably consider
     and discuss in good faith Parent's proposals, and (iv) prior to or
     concurrently with the Company's termination pursuant to this Section
     7.1(f), the Company pays to Parent the fee required by Section 7.3 to be
     paid to Parent in the manner therein provided. The Company agrees (x) that
     it will not enter into a binding agreement referred to in clause (ii) above
     until at least the sixth business day after Parent has received the notice
     to Parent required by clause (ii) above, and (y) to notify Parent promptly
     if its intention to enter into the binding agreement included in its notice
     to Parent shall change at any time after giving such notice;

          (g) by Parent if (i) Parent is not in material breach of its
     obligations under this Agreement and (ii) there has been a material breach
     by the Company of any of its representations, warranties, or obligations
     under this Agreement such that the conditions in Section 6.3 will not be
     satisfied ("Terminating Company Breach"); provided, however, that, if such
     Terminating Company Breach is curable by the Company through the exercise
     of commercially reasonable efforts and such cure is reasonably likely to be
     completed prior to the applicable date specified in Section 7.1(b), then
     for so long as the Company continues to exercise commercially reasonable
     efforts, Parent may not terminate this Agreement under this Section 7.1(g);
     or

          (h) by the Company if (i) the Company is not in material breach of its
     obligations under this Agreement and (ii) there has been a material breach
     by Parent of any of its representations, warranties, or obligations under
     this Agreement such that the conditions in Section 6.2 will not be
     satisfied ("Terminating Parent Breach"); provided, however, that, if such
     Terminating Parent Breach is curable by Parent through the exercise of
     commercially reasonable efforts and such cure is reasonably likely to be
     completed prior to the applicable date specified in Section 7.1(b), then
     for so long as Parent continues to exercise commercially reasonable
     efforts, the Company may not terminate this Agreement under this Section
     7.1(h).

     SECTION 7.2  Effect of Termination. The party desiring to terminate this
Agreement shall give written notice of such termination to the other party.
Except for any willful breach of this Agreement by any party hereto (which
willful breach and liability therefor shall not be affected by the termination
of this Agreement or the payment of any Termination Fee (as defined in Section
7.3(a) hereof)), if this Agreement is terminated pursuant to Section 7.1 hereof,
then this Agreement shall become void and of no effect with no liability on the
part of any party hereto; provided, however that notwithstanding such
termination the agreements contained in Sections 5.2, 5.4(b), 7.2, 7.3, 7.4 and
Article VIII hereof shall survive the termination hereof.

     SECTION 7.3  Fees.

     (a) The Company agrees to pay Parent in immediately available funds by wire
transfer to an account designated by Parent an amount equal to One Hundred Eight
Million Dollars ($108,000,000) (the "Termination Fee") if:

          (i) this Agreement is terminated by Parent pursuant to Section 7.1(d)
     (ii) through (iv) hereof; or

          (ii)(A) this Agreement is terminated by Parent or the Company pursuant
     to Section 7.1(b), 7.1(d)(i) or 7.1(e) hereof, (B) at or prior to the time
     of such termination, an Acquisition Proposal with respect to the Company
     shall have been made public and remains pending at the time of such
     termination or at the time of the Company Stockholders' Meeting, and (C)
     within twelve months after such termination, the Company shall enter into a
     definitive agreement with respect to any Acquisition Proposal or the
     transaction contemplated by any Acquisition Proposal relating to the
     Company shall be consummated; or

          (iii) this Agreement is terminated by the Company pursuant to Section
     7.1(f) hereof.

     (b) The Company shall pay the Termination Fee required to be paid pursuant
to Section 7.3(a) hereof (if all conditions thereto have been satisfied) (i)
prior to or concurrently with the termination of this Agreement by the Company,
(ii) not later than one business day after the termination of this Agreement by
Parent, or (iii) in the case of a fee payable pursuant to Section 7.3(a)(ii),
prior to the earlier of the execution

                                       A-32
   107

of the definitive agreement with respect to, or the consummation of the
transaction contemplated by, the applicable Acquisition Proposal.

     SECTION 7.4  No Penalty; Costs of Collection. The Company acknowledges that
the agreements contained in Section 7.3 are an integral part of the transactions
contemplated by this Agreement and are not a penalty, and that, without these
agreements, Parent would not enter into this Agreement. If the Company fails to
pay promptly the fee due pursuant to this Section 7.3, the Company shall also
pay to Parent Parent's costs and expenses (including legal fees and expenses) in
connection with any action, including the filing of any lawsuit or other legal
action, taken to collect payment, together with interest on the amount of the
unpaid fee under this section, accruing from its due date, at an interest rate
per annum equal to the prime commercial lending rate quoted by Wells Fargo Bank
Minnesota, N.A.; provided, however, that Parent shall pay to the Company the
Company's costs and expenses (including legal fees and expenses) incurred in
connection with any such legal action if Parent's claims against the Company in
such legal action do not prevail. Any change in the interest rate hereunder
resulting from a change in such prime rate shall be effective at the beginning
of the date of such change in such prime rate.

representations and warranties of Parent and the Company contained herein or in
any certificates or other documents delivered prior to or at the Closing shall
not be deemed waived or otherwise affected by any investigation made by any

contemplated hereby, the representations and warranties contained herein and in

subsequent to the Effective Time, shall survive the Merger in accordance with
their terms.

     SECTION 8.3  Interpretation. Whenever the words "include," "includes" or
"including" are used in this Agreement they shall be deemed to be followed by
the words, "but not limited to." As used in this Agreement, the term "affiliate"

Act.

     The article and section headings contained in this Agreement are solely for
the purpose of reference, are not part of the agreement of the parties hereto
and shall not in any way affect the meaning or interpretation of this Agreement.
Any matter disclosed pursuant to any Schedule of the Company Disclosure Schedule
shall not be deemed to be an admission or representation as to the materiality
of the item so disclosed.

     SECTION 8.4  Amendments, Modification and Waiver.

     (a) Except as may otherwise be provided herein, any provision of this
Agreement may be amended, modified or waived by the parties hereto, by action
taken by or authorized by their respective Board of Directors, prior to the
Closing Date if, and only if, such amendment or waiver is in writing and signed,
in the case of an amendment, by the Company and Parent or, in the case of a
waiver, by the party against whom the waiver is to be effective; provided that
after the adoption of this Agreement by the stockholders of the Company, no such
amendment shall be made except as allowed under applicable law.

     (b) No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

     SECTION 8.5  Successors And Assigns. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided that neither the Company nor Parent
may assign, delegate or otherwise transfer any of its rights or obligations
under this Agreement without the consent of the other parties hereto.

     SECTION 8.6  Specific Performance. The parties acknowledge and agree that
any breach of the terms of this Agreement would give rise to irreparable harm
for which money damages would not be an adequate remedy and accordingly the
parties agree that, in addition to any other remedies, each shall be entitled to
enforce the terms of this Agreement by a decree of specific performance without
the necessity of proving the inadequacy of money damages as a remedy.

     SECTION 8.7  Governing Law and Venue. This Agreement shall be governed by
and construed in accordance with the laws of the State of Delaware (regardless
of the laws that might otherwise govern under applicable principles of conflicts
of laws thereof) as to all matters, including matters of validity, construction,
effect, performance and remedies. The parties hereby (i) agree and consent to be
subject to the exclusive jurisdiction of any state or federal court in the State
of Delaware with respect to all actions and proceedings

                                       A-34
   109

arising out of or relating to this Agreement (and each party agrees not to bring
any such action or proceeding in any other jurisdiction to which the other party
is subject); (ii) agree that all claims with respect to any such action or
proceeding may be heard and determined in such court; (iii) irrevocably waive
any defense of an inconvenient forum to the maintenance of any action or
proceeding in such court; (iv) consent to service of process by mailing or
delivering such service to the party at its respective principal business
address; and (v) agree that a final judgment in any such action or proceeding
from which there is no further appeal shall be conclusive and may be enforced in
any other jurisdictions by suit on the judgment or in any manner provided by
law.

     SECTION 8.8  Severability. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated herein are not affected in any manner materially
adverse to any party hereto. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner.

     SECTION 8.9  Third Party Beneficiaries. This Agreement is solely for the
benefit of the Company and its successors and permitted assigns, with respect to
the obligations of Parent and Merger Sub under this Agreement, and for the
benefit of Parent and Merger Sub, and their respective successors and permitted
assigns, with respect to the obligations of the Company under this Agreement,
and this Agreement shall not, except to the extent necessary to enforce the
provisions of Article I and Section 5.6 and 5.11 hereof be deemed to confer upon
or give to any other third party any remedy, claim, liability, reimbursement,
cause of action or other right.

     SECTION 8.10  Entire Agreement. This Agreement, including any exhibits or
schedules hereto and the Confidentiality Agreement constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and
supersedes all other prior agreements or understandings, both written and oral,
between the parties or any of them with respect to the subject matter hereof.

     SECTION 8.11  Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be deemed an original, with the
same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement shall become effective when each party hereto shall
have received counterparts hereof signed by all of the other parties hereto.

     SECTION 8.12  Definitions. Each of the following terms is defined in the
Section set forth opposite such term.

                         AGREEMENT TO FACILITATE MERGER

DATE:
- ---------------, 2001

PARTIES:

          Medtronic, Inc.,                                (hereinafter "Parent")
          a Minnesota corporation

               and

- ------------------------, an individual officer and/or director
          of MiniMed Inc.                        (hereinafter "Security Holder")

RECITALS:

     A.  Security Holder is the legal or beneficial owner of shares of Common
Stock of MiniMed Inc., a Delaware corporation (the "Company"), and/or the holder
of options, warrants, or other rights to acquire shares of Company Common Stock.

     B.  Parent, the Company, and a wholly-owned subsidiary of Parent are
entering, or have entered, into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which it is proposed that Parent's subsidiary will merge
with and into the Company (the "Merger") and as a result of which the
outstanding shares of Company Common Stock shall be converted into the right to
receive a cash payment.

     C.  Security Holder deems it to be in Security Holder's best interest and
in the best interests of the Company and all other stockholders of the Company
that the Merger Agreement be approved, ratified, and confirmed by the
stockholders of the Company, and it is a condition to Parent's obligations under
the Merger Agreement that Security Holder enter into this Agreement.

     D.  It is understood and acknowledged by Security Holder that Parent's
execution of the Merger Agreement is being done in reliance, in part, upon the
contemporaneous execution and delivery of this Agreement, that Parent will incur
substantial expenses proceeding toward consummation of the Merger as
contemplated by the Merger Agreement, and that such expenses will be undertaken,
in part, in reliance upon and as a result of the agreements and undertakings of
Security Holder set forth herein.

     NOW, THEREFORE, in consideration of the foregoing, and in order to induce
Parent to execute the Merger Agreement and to proceed as contemplated by the
Merger Agreement toward the consummation of the Merger, and for other good and
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

AGREEMENTS:

     1. Vote in Favor of Merger. During the period commencing on the date hereof
and terminating upon the earlier of (i) the effective time of the Merger, and
(ii) the termination of the Merger Agreement in accordance with its terms,
Security Holder agrees to vote (or cause to be voted) all shares of Company
Common Stock presently beneficially owned by Security Holder, and all shares of
Company Common Stock with respect to which Security Holder in the future
acquires beneficial ownership, at any meeting of the stockholders of the
Company, and in any action by written consent of the stockholders of the
Company, in favor of the approval, consent, and ratification of the Merger
Agreement and the Merger and against any proposal or action that could impede,
interfere, frustrate, nullify or discourage the Merger, could facilitate an
acquisition of the Company, in any manner, by a party (other than Parent), or
could reasonably result in any of the conditions to the Company's obligations
under the Merger Agreement not being fulfilled. To the extent inconsistent with
the foregoing provisions of this Section 1, Security 1-folder hereby revokes any
and all previous proxies with respect to any shares of Company Common Stock that
Security Holder owns or has the

                                       A-41
   116

right to vote. Nothing in this Agreement shall be deemed to restrict or limit
Security Holder's right to act in his capacity as an officer or director of the
Company consistent with his fiduciary obligations in such capacity.

     2. Representations and Warranties of Security Holder. Security Holder
represents and warrants to Parent that Security Holder has the legal capacity to
enter into and perform all of Security Holder's obligations under this
Agreement. The execution, delivery, and performance of this Agreement by
Security Holder will not violate any other agreement to which Security Holder is
a party, including, without limitation, any voting agreement, stockholders
agreement, or voting trust. This Agreement has been duly executed and delivered
by Security Holder and constitutes a legal, valid, and binding agreement of
Security Holder, enforceable in accordance with its terms, except as the
enforcement thereof may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium, and similar laws, now or hereafter in
effect.

     3. Successors and Assigns. This Agreement shall be binding upon any
purchasers, donees, pled gees, and other transferees of Company Common stock
legally or beneficially owned by Security Holder. During the period commencing
on the date hereof and terminating upon the earlier of the effective time of the
Merger and the termination of the Merger Agreement in accordance with its terms,
Security Holder agrees not to make any sales, gifts, transfers, pledges, or
other dispositions of Company Common Stock without first making any such
transferee or pledgee fully aware of Security Holder's obligations under this
Agreement and obtaining such transferee's or pledgee's written agreement to
comply with all terms hereof.

     4. Injunctive Relief. Security Holder agrees that in the event of Security
Holder's breach of any provision of this Agreement, Parent may be without an
adequate remedy at law. Security Holder therefore agrees that in the event of
Security Holder's breach of any provision of this Agreement, Parent may elect to
institute and prosecute proceedings in any court of competent jurisdiction to
enforce specific performance or to enjoin the continuing breach of such
provision, as well as to obtain damages for breach of this Agreement. By seeking
or obtaining any such relief, Parent will not be precluded from seeking or
obtaining any other relief to which it may be entitled.

     5. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same document.

     6. Further Assurances. Security Holder shall execute and deliver such
additional documents and take such further action as may be necessary or
desirable to consummate the transactions contemplated by this Agreement.

     7. Third-Party Beneficiaries. Nothing in this Agreement, expressed or
implied, shall be construed to give any person other than the parties hereto any
legal or equitable right, remedy. or claim under or by reason of this Agreement
or any provision contained herein.

     8. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (regardless of the laws that
might otherwise govern under applicable Delaware principles of conflicts of
laws).

     9. Effectiveness. If this Agreement is executed by Security Holder prior to
the approval of the Merger Agreement by the Company's Board of Directors, then
this Agreement shall be subject to, and shall become effective only upon, the
approval of the Merger Agreement by the Company's Board of Directors and the
execution and delivery of the Merger Agreement by the Company, Parent and
Parent's subsidiary. This Agreement shall terminate upon termination of the
Merger Agreement in accordance with its terms.

                                       A-42
   117

     IN WITNESS WHEREOF, Parent has caused this Agreement to Facilitate Merger
to be executed by its duly authorized officer, and Security Holder has executed
this Agreement, as of the date and year first above written.

                                  May 30, 2001


The Board of Directors
MiniMed Inc.
18000 Devonshire Street
Northridge, California 91342
Dear Members of the Board:

     We understand that MiniMed Inc. ("MiniMed") and Medtronic, Inc.
("Medtronic") propose to enter into an Agreement and Plan of Merger, dated as of
May 30, 2001 (the "Agreement"), by and among MiniMed, Medtronic and MMI Merger
Corp., a wholly owned subsidiary of Medtronic ("Merger Sub"), pursuant to which
Merger Sub will be merged with and into MiniMed (the "Merger") and each
outstanding share of the common stock, par value $0.01 per share, of MiniMed
("MiniMed Common Stock") will be converted into the right to receive $48.00 in
cash (the "Merger Consideration"). The terms and conditions of the Merger are
more fully set forth in the Agreement.

     You have requested our opinion as to the fairness, from a financial point
of view, of the Merger Consideration to the holders of MiniMed Common Stock.

     UBS Warburg LLC ("UBS Warburg") has acted as financial advisor to MiniMed
in connection with the Merger and will receive a fee for its services, a
significant portion of which is contingent upon the consummation of the Merger.
UBS Warburg also will receive a fee in connection with the delivery of this
opinion. UBS Warburg and its affiliates in the past have provided services to
MiniMed and Medtronic unrelated to the proposed Merger, for which services UBS
Warburg and its affiliates have received compensation. In the ordinary course of
business, UBS Warburg, its successors and affiliates may trade securities of
MiniMed and Medtronic for their own accounts and accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

     Our opinion does not address MiniMed's underlying business decision to
effect the Merger and does not constitute a recommendation to any stockholder of
MiniMed as to how such stockholder should vote with respect to any matter
relating to the Merger. We have not been asked to, nor do we, offer any opinion
as to the terms of the Agreement (other than with respect to the Merger
Consideration to the extent expressly stated herein) or related documents and
the obligations thereunder, or the form of the Merger. In rendering this
opinion, we have assumed, with your consent, that each of MiniMed, Medtronic and
Merger Sub will comply with all material covenants and agreements set forth in,
and other material terms of, the Agreement and related documents and that the
Merger will be consummated in accordance with its terms without waiver,
modification or amendment of any material term, condition or agreement.

     In arriving at our opinion, we have, among other things: (i) reviewed
current and historical market prices and trading volumes of MiniMed Common
Stock; (ii) reviewed certain publicly available business and historical
financial information relating to MiniMed; (iii) reviewed certain internal
financial information and other data relating to the business and financial
prospects of MiniMed, including estimates and financial forecasts prepared by
the management of MiniMed, that were provided to or discussed with us by MiniMed
and not publicly available; (iv) conducted discussions with members of the
senior management of MiniMed; (v) reviewed publicly available financial and
stock market data with respect to certain companies in lines of business we
believe to be generally comparable to those of MiniMed; (vi) compared the
financial terms of the Merger with the publicly available financial terms of
certain other transactions which we believe to be generally relevant; (vii)
reviewed the Agreement and certain related documents; and (viii) conducted such
other financial studies, analyses and investigations, and considered such other
information, as we deemed necessary or appropriate.

     In connection with our review, with your consent, we have not assumed any
responsibility for independent verification of any of the information provided
to or reviewed by us for the purpose of this opinion and have, with your
consent, relied on its being complete and accurate in all material respects. In
addition, at your direction, we have not made any independent evaluation or
appraisal of any of the assets or liabilities (contingent or otherwise) of
MiniMed, nor have we been furnished with any such evaluation or appraisal. With
respect to the financial forecasts and estimates referred to above relating to
MiniMed, we have assumed, at your direction, that they have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the management of MiniMed as to the future financial performance of
MiniMed. In connection with our engagement, we were requested to solicit
indications of interest from, and held discussions with, selected third parties
regarding the possible acquisition of all or a part of MiniMed. Our opinion is
necessarily based on economic, monetary, market and other conditions as in
effect on, and the information made available to us as of, the date of this
letter.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Consideration is fair, from a financial point of view,
to the holders of MiniMed Common Stock.

                                          Very truly yours,

[U.S. BANCORP PIPER JAFFRAY LOGO]

May 29, 2001

The Special Committee of the Board of Directors
MiniMed Inc.
1800 Devonshire Street
Northridge, CA 91325

Members of the Special Committee of the Board:

     You have requested our opinion as of the date hereof as to the fairness,
from a financial point of view, to the holders of common stock (the "Common
Stock") of MiniMed Inc. ("MiniMed" or "Company") of the proposed cash
consideration to be paid to the holders of MiniMed Common Stock (other than
Parent, Merger Sub and their affiliates) pursuant to an Agreement and Plan of
Merger (the "Agreement"), among MiniMed, Medtronic, Inc. ("Parent") and MMI
Merger Corp ("Merger Sub"), a wholly owned subsidiary of Parent. Pursuant to the
Agreement, Merger Sub will be merged with and into the Company ("Merger") and
each outstanding share of Company Common Stock will convert into the right to
receive $48.00 per share in cash ("Merger Consideration") (collectively, the
"Transaction"). The terms and conditions of the Merger are more fully set forth
in the Agreement.

     U.S. Bancorp Piper Jaffray Inc., as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwriting and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes. We have acted as a financial advisor to The
Special Committee of the Board of Directors of MiniMed in connection with the
Agreement and will receive a fee for providing this opinion. This opinion fee is
not contingent upon the consummation of the Transaction. MiniMed has also agreed
to indemnify us against certain liabilities in connection with our services. We
make a market in the Common Stock and provide research coverage for MiniMed and
Parent. In the past, we have provided investment banking services to Parent on
unrelated transactions. In the ordinary course of our business, we and our
affiliates may actively trade securities of MiniMed and Parent for our own
account or the account of our customers and, accordingly, may at any time hold a
long or short position in such securities.

     In arriving at our opinion, we have undertaken such review, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have reviewed (i) a draft copy of the Agreement dated May 29,
2001, (ii) certain financial, operating, business and other information relative
to MiniMed that was publicly available or furnished by the management of
MiniMed, (iii) to the extent publicly available, the stock price premiums paid
and financial terms of certain acquisition transactions involving companies
operating in industries in which MiniMed operates and operating performance and
valuation analyses of selected public companies deemed comparable to MiniMed,
and (iv) certain publicly available market and securities data of MiniMed. In
addition, we had discussions with members of the management of MiniMed
concerning the financial condition, current operating results and business
outlook for MiniMed on a stand-alone basis.

     We have relied upon and assumed the accuracy, completeness and fair
presentation of the financial statements and accuracy and completeness of other
information provided to us by MiniMed, or otherwise made available to us, and
have not assumed responsibility for the independent verification of such
information. We have relied upon the assurances of the management of MiniMed
that the information provided to us by

                                       C-1
   121

MiniMed has been prepared on a reasonable basis, and, with respect to financial
planning data and other business outlook information, reflects the best
currently available estimates and judgement of MiniMed's management, and that
they are not aware of any information or facts that would make the information
provided to us incomplete or misleading. We have also assumed that there have
been no material changes to MiniMed's assets, financial condition, results of
operations, business or prospects since the date of their last financial
statements made available to us. We have relied on advice of counsel and
independent accountants to MiniMed as to all legal, financial reporting and
accounting matters. We have assumed that the Transaction will be consummated in
a manner that complies in all respects with the applicable provisions of the
Securities Act of 1933, as amended (the "Securities Act"), the Securities
Exchange Act of 1934 and all other applicable federal and state statutes, rules
and regulations.

     We have assumed with your consent that the final form of the Agreement will
be substantially similar to the last draft reviewed by us, without modification
of material terms or conditions. We have assumed with your consent that the
Transaction will be consummated in accordance with the terms described in the
Agreement without any further amendments thereto and without waiver by any party
of any of the conditions to its obligations thereunder.

     We have assumed with your consent that the terms of the Transaction are the
most beneficial terms from MiniMed's perspective that could under the
circumstances be negotiated among the parties to such transaction, and no
opinion is expressed as to whether any alternative transaction would be more
beneficial to MiniMed. Our opinion does not address, nor should it be construed
to address, the relative merits of the Transaction, on the one hand, or any
alternative business strategies that may be available to MiniMed, on the other
hand. We were not requested to opine as to, and this opinion does not address,
the basic business decision to proceed with or effect the Transaction.

     In arriving at our opinion, we have not performed any appraisals or
valuations of any specific assets or liabilities of MiniMed, and have not been
furnished with any such appraisals or valuations. We express no opinion
regarding the liquidation value of any entity. We have assumed, at your
direction, that all conditions to consummation of the Transaction contained in
the Agreement will be obtained or satisfied, including all necessary regulatory
approvals and Transaction financings by Parent.

     This opinion is necessarily based upon the information available to us and
facts and circumstances as they exist and are subject to evaluation on the date
hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion. We are not expressing any opinion
herein as to the price at which shares of MiniMed Common Stock have traded or
may trade at any future time. We have not undertaken to reaffirm or revise this
opinion or otherwise comment upon any events occurring after the date hereof and
do not have any obligation to update, revise or reaffirm this opinion.

     This opinion is solely for the benefit of the Special Committee of the
Board of Directors in connection with its consideration of the Transaction and
may not be relied upon by any other person. This opinion is not intended to be
and does not constitute a recommendation to any stockholder of MiniMed. The
Agreement provides that prior to or concurrently with the closing of the
Transaction, Parent will acquire all of the equity interests in Medical Research
Group, Inc. ("MRG"). Alfred Mann, the Chief Executive Officer and Chairman of
the Board of Directors of MiniMed, is also a controlling shareholder and member
of the Board of Directors of MRG. This opinion does not address the fairness of
the consideration to be paid to the stockholders of MRG. This opinion shall not
be published or otherwise used, nor shall any public references to us or this
opinion be made, without our prior written approval, except that this opinion
may be included in its entirety in any filing made by MiniMed in respect of the
Transaction with the Securities and Exchange Commission, so long as this opinion
is reproduced in such filing in full and any description or reference to us or
this opinion and related analysis in such filing is in a form acceptable to us
and our counsel. In furnishing this opinion, we do not admit that we are experts
within the meaning of the term "experts" in the Securities Act nor do we admit
that this opinion constitutes a report or valuation within the meaning of
Section 11 of the Securities Act.

     Based upon and subject to the foregoing and based upon such other factors
as we consider relevant, it is our opinion, as of the date hereof, that the
consideration of $48.00 per share in cash, proposed to be received in the
Transaction by the stockholders of MiniMed (other than Parent, Merger Sub and
their affiliates) pursuant to the Agreement, is fair, from a financial point of
view, to such stockholders.

                                  Sincerely,

SECTION 262. APPRAISAL RIGHTS

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 64 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs paragraphs a. and b.
        of this paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs paragraphs a., b. and c. of
        this paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate

                                       D-1
   124

of incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection section and has not voted
     in favor of or consented to the merger or consolidation of the date that
     the merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to Section
     228 or Section 253 of this title, then, either a constituent corporation
     before the effective date of the merger or consolidation, or the surviving
     or resulting corporation within ten days thereafter, shall notify each of
     the holders of any class or series of stock of such constituent corporation
     who are entitled to appraisal rights of the approval of the merger or
     consolidation and that appraisal rights are available for any or all shares
     of such class or series of stock of such constituent corporation, and shall
     include in such notice a copy of this section. Such notice may, and, if
     given on or after the effective date of the merger or consolidation, shall,
     also notify such stockholders of the effective date of the merger or
     consolidation. Any stockholder entitled to appraisal rights may, within 20
     days after the date of mailing of such notice, demand in writing from the
     surviving or resulting corporation the appraisal of such holder's shares.
     Such demand will be sufficient if it reasonably informs the corporation of
     the identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the
                                       D-2
   125

effective date of the merger or consolidation, any stockholder shall have the
right to withdraw such stockholder's demand for appraisal and to accept the
terms offered upon the merger or consolidation. Within 120 days after the
effective date of the merger or consolidation, any stockholder who has complied
with the requirements of subsections (a) and (d) hereof, upon written request,
shall be entitled to receive from the corporation surviving the merger or
resulting from the consolidation a statement setting forth the aggregate number
of shares not voted in favor of the merger or consolidation and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares. Such written statement shall be mailed to the
stockholder within 10 days after such stockholder's written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

                                       D-3
   126

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
